Shortcut

How about WT:DOUBLE-E/WP:DOUBLE-E being shortcuts for this project? (talk page, main page) -- 70.24.251.208 (talk) 08:52, 16 June 2012 (UTC)

EE, Eengg, ele engg would be fine. do you think double is req? ShriRam^{Talk to}_me 09:06, 16 June 2012 (UTC)

WP:EE and WP:WPEE is already in use. I suppose we could ask that WPP to let us have "WP:EE" or "WP:WPEE" instead. That's why I suggested "Double-E". WP:ELECENG/WP:EENG sound good. 70.49.127.65 (talk) 18:38, 16 June 2012 (UTC)

I have rerouted the redirect of WP:ENGG to WikiProject Engineering, since Engg. is an abbreviation for Engineering, not just Electrical Engineering. So this could be confusing. But I have added WP:EEng, since EEng. seem to be also a common abbreviation for Electrical Engineering. Regards, SchreyP ^(messages) 12:24, 13 July 2012 (UTC)

Banner template

Ok, here's a sample banner template: Wikipedia talk:WikiProject Electrical Engineering/banner, which uses Wikipedia talk:WikiProject Electrical Engineering/banner/class and Wikipedia talk:WikiProject Electrical Engineering/banner/importance; documentation at Wikipedia talk:WikiProject Electrical Engineering/banner/doc. If we use this one, it will need to be moved to Template:WikiProject Electrical Engineering and Template:WikiProject Electrical Engineering/importance , Template:WikiProject Electrical Engineering/class , Template:WikiProject Electrical Engineering/doc respectively, and the redlinked categories will need to be created, along with the intersection of those categories. 70.24.251.208 (talk) 08:45, 16 June 2012 (UTC)

Nice ones, especially Wikipedia talk:WikiProject Electrical Engineering/banner, because electrical engineers know the importance of grounding. I've created a userbox. I hope its good. ShriRam^{Talk to}_me 09:04, 16 June 2012 (UTC)

looks good. I see you reduced the complexity of the banner. You (since an IP cannot create things) need to create the assessment categories (look at the banner page for a list of categories to create). I've done some initial tagging for a few high prominence pages. -- 70.49.127.65 (talk) 18:35, 16 June 2012 (UTC) (my IP has rotated)

I'll have a look. But the process might go slow due to my exams! ShriRam^{Talk to}_me 18:37, 16 June 2012 (UTC)

Sure, no problem. Whenever you have time, or someone else joins who has an account. 70.49.127.65 (talk) 18:41, 16 June 2012 (UTC)

In addition to the categories listed in the fix-me autonotices on the banner page, we also need the two parent categories Category:WikiProject Electrical Engineering articles by importance‎ and Category:WikiProject Electrical Engineering articles by quality, which categorize directly into Category:WikiProject Electrical Engineering. -- 70.49.127.65 (talk) 18:52, 16 June 2012 (UTC)

Synchronous motor

This article is rated "high priority" by your project, but is currently the subject of an editing dispute because it is largely unsourced. The editor arguing for removing the content is technically in the right since this is a technical article and needs to be verifiable, but it would be a shame if good content was removed on that basis. I have tracked down some sources on Google Books preview which may be of use, but this isn't my area, and I would not feel comfortable adding references to an article where I am not familiar with the subject matter. If someone could spend an hour or two adding some sources to diffuse the situation it would be appreciated. Betty Logan (talk) 17:38, 15 December 2012 (UTC)

WaveletPackets

The equations given for the number wavelet sets of coefficients does not look right. "For n levels of decomposition the WPD produces 2^n different sets of coefficients (or nodes) as opposed to (3n + 1) sets for the DWT. However, due to the downsampling process the overall number of coefficients is still the same and there is no redundancy."

2^n looks smaller than what it should be. also 3n+1 doens't work for DWT for 1D signal with 2levels. — Preceding unsigned comment added by 143.215.149.156 (talk) 21:14, 7 June 2013 (UTC)

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time!

Donation of images for electromagnetism articles

Simulated electric field around a printed inverted-F antenna.

Multipaction within the gap inside a coaxial connector, driven by fields between the conductors. Color represents electron energy

(Cross-posted to Wikipedia talk:WikiProject Physics)

Hello everyone. I'm Stephen Murray, the Technical Writer for Computer Simulation Technology, who focus on electromagnetic simulation tools. One thing that we have recently realized is that we currently have quite a few example images/simulation models which illustrate devices and physical phenomena that Wikipedia doesn't currently have. Chiefly, these consist of various models of antennas, microwave filters and waveguide components, particle accelerator components and some nano-optical/photonic devices. We would like to donate images where we can in order to improve Wikipedia's coverage of these topics.

On the right are a couple of example pictures from our selection (illustrating microstrip antenna and multipactor effect respectively) - would these be helpful to the project? Because we have the simulation models, it would take relatively little effort on my end to adjust the angle of view or the field display. It's just a question of how to make these images as useful to the encyclopedia as possible. Any comments or suggestions would therefore be appreciated.

Hello everyone!

You may have received a message from me earlier asking you to comment on my WikiProject X proposal. The good news is that WikiProject X is now live! In our first phase, we are focusing on research. At this time, we are looking for people to share their experiences with WikiProjects: good, bad, or neutral. We are also looking for WikiProjects that may be interested in trying out new tools and layouts that will make participating easier and projects easier to maintain. If you or your WikiProject are interested, check us out! Note that this is an opt-in program; no WikiProject will be required to change anything against its wishes. Please let me know if you have any questions. Thank you!

Note: To receive additional notifications about WikiProject X on this talk page, please add this page to Wikipedia:WikiProject X/Newsletter. Otherwise, this will be the last notification sent about WikiProject X.

Three articles, two concepts

We have Volt, voltage and electric potential. It seems to me that we have three articles, but only two concepts (a physical force and its measurement). My first instinct is to merge voltage to volt, since volt is by far the weakest article, but more input would be welcome. Oiyarbepsy (talk) 19:11, 18 February 2015 (UTC)

Hmm, Volt is an SI derived unit, electric potential is a term used for both electrostatic potential and the scalar potential in the electrodynamic case, and voltage is the difference between electric potentials at two points in space or in a circuit. While the three are related, I see each as a different concept. And none of them are forces in the physics sense. --Mark viking (talk) 20:43, 18 February 2015 (UTC)

There seems to be a fourth article: Electromotive force. I'm an EE and don't split hairs on this stuff. We should not expect readers to have to deal with this as they introduce themselves to the topic. Of course the gory details can be explained in the article body or bodies but having an introduction to a topic involving such technical definitions and spread over several articles is definitely a problem. Mark viking, if you oppose a merge, do you have any suggestions for making the topic more accessible? ~Kvng (talk) 14:13, 7 April 2015 (UTC)

I'm a physicist with a minor in EE, and back in undergrad, my fellow EEs definitely knew the difference between capacitance and a Farad, just as they knew the difference between a volt and voltage. More generally, at the undergraduate level,

1. Maxwell's equations leads to the concept of an electric field.
2. The electric field is a conservative vector field in that line integrals of the electric field depend only on the endpoints. This allows one to represent the electric field as a scalar electric potential.
3. The difference in potential between two points is the voltage. Electromotive force is the voltage developed by a source such as a battery or generator.
4. The numerical value for voltage depends on the unit of measurement; the volt is the most common.

And people learn about the difference between field, potential and voltage even in (US) high-school physics. So I think the difference between these topics is much more than splitting hairs.

That said, I'm not opposed to a careful merger of electric potential, electromotive force, voltage, with targeted redirects to the proper sections. I'd leave volt out of it, it is easy enough to confuse volt and voltage as it is. I understand the desire for an accessible introduction. An alternative to merge would we to develop an introductory article. Right now voltage is more simply written than the other two and could become the nucleus of an intro article. --Mark viking (talk) 21:04, 13 April 2015 (UTC)

Volt should not be merged with voltage or electric potential. Physical quantities are different from their units, and should be treated as separate entities, same as with ampere and electric current, and metre and length. For example, the history of the units is mostly irrelevant to the physical quantities, so it belongs only in a discussion of the units.

However, it may be good to merge electric potential as a section in voltage. In engineering practice, voltage can often but not always be expressed as a difference of potentials (see Fundamental theorem of vector calculus). However, in a real transformer with a secondary in a loop (therefore shorted) there is no meaningful way to assign a potential to each point of the loop. The secondary can be analyzed as a resistor and the secondary of an ideal transformer, so as to make possible to assign voltage potentials, but that is a construct that doesn't corresponds to the physical situation. If we conceptualize the loop as infinitely many ideal transformers secondaries interleaved with infinitely many resistors, then it becomes clear why there is no way to assign a potential: because the elements are distributed and in each section, the induced voltage in the transformers secondaries equals the voltage drop in the resistors.

Regards. Mario Castelán Castro (talk) 16:40, 14 April 2015 (UTC).

Looks like Mark viking and Mario Castelán Castro would accept a merge of electric potential into voltage but volt should not be involved. Mario Castelán Castro, do you have any comment about electromotive force? ~Kvng (talk) 15:15, 18 April 2015 (UTC)

My 2 cents worth.

• Volt is about the unit of measurement and should be a separate article.

Everything else is tied together by the equation E = -∇(φ) -σA/σt, where φ is the electrodynamic retarted electric scalar potential and A is the retarded magnetic vector potential.

• Voltage is, to me, a circuit quantity. It’s what a voltmeter would read between two points in a circuit. If the leads to the voltmeter went through a region where σA/σt ≠ 0, then the voltmeter reading would depend on the path of the leads to the voltmeter and the voltage would be ill defined.

• Electromotive force, I usually associate with a path integral of the electric field (as defined above) tangential to a definite path. Usually the path follows a conductor. Typical paths may include a battery, generator, transformer, loop antenna, microphone, transducer. EMF for a specific path is unique. The path may be implicit. In a particular usage, there may be no mention of the path integral, but it is there never-the-less. If the beginning point and ending point of the path integral were in a continuous region where σA/σt = 0 then the voltage measured between those points by a voltmeter connected to those points and entirely in the region would read a unique value and EMF would numerically be the same as the voltage.

• Potential has more than one meaning. The article will have to deal with that. For me, potential is a field quantity, although potential is used as a synonym for voltage in both DC and AC circuits.

- The electrodynamic retarded scalar electric potential, which is used above in the equation for E. It is well defined everywhere except for points occupied by point charges. The difference in potential between two points is also well defined but may be physically meaningless. In general, the potential difference between two points is not the voltage between those two points.

Rotating electrical machine articles need some attention.

• Doubly fed electric machine - This is just unreadable, and the first sentence of the lede seems wrong. See Talk:Doubly fed electric machine. There's a COI problem with this article, but it is a real technology.
• Armature - do these edits [1] make any sense? Some of this reads like it was machine-translated from a language with much longer sentences than English.

I'm not an electrical-machine expert. Can someone take a look at these? Thanks. John Nagle (talk) 08:13, 2 January 2016 (UTC)

Regarding armature- yes, it is terrible. Constant314 (talk) 20:21, 2 January 2016 (UTC)

I just noticed that the disambiguation page for field leads to stator. That's wrong. "Rotor" and "stator", and "armature" and "field" are independent. Sometimes (especially for large generators) the field is on the rotor and the output is on the armature.[2][3]. We need a separate article for "Field (electrical machine)" John Nagle (talk) 20:24, 2 January 2016 (UTC)

We have field magnet, so I had the disambiguation page for field link there. John Nagle (talk) 20:30, 2 January 2016 (UTC)

Can anyone with a background in rotary electric machines help with Doubly-fed electric machine? It's mostly been written by a COI editor who has patents in that area. But that's not the problem. The language is unreadable. It reads like machine-translated German. (One sentence: "Only practical with the evolution of control technology that avoids instability and discontinuity over the sub-synchronous to super-synchronous speed range, particularly at synchronous speed where induction ceases to exist, there are now three varieties of doubly-fed electric machine systems: 1) the Doubly-Fed Induction Electric Machine (DFIM), which is the conventional wound-rotor doubly-fed electric machine with an active winding set on the rotor and stator, respectively, and flux vector controlled rotor excitation through a multiphase slip-ring assembly; 2) the Brushless Doubly-Fed Induction Electric Machine (BDFIM), which is the brushless doubly-fed induction (or reluctance) electric machine with cascaded active winding sets of unlike pole-pairs on the stator assembly of which one is flux vector controlled and a flux focusing rotor assembly; and 3) Synchro-Sym electric machine system, which is the only Brushless Doubly Fed Synchronous Electric Machine (BDFSM).")

48 volts is a commonly used as dividing point between signal and power electronics but there are examples of low-voltage power systems and high-voltage signal systems.

Is Home Idle Load a neologism?

I'm aware of the problem of devices which consume standby power, but I've never heard it be referred to as Home Idle Load. Would somebody with a knowledge of power distribution kindly review this article? --Salimfadhley (talk) 23:04, 15 August 2017 (UTC)

Me neither. I did a google search on Home idle load with double quotes (not home's idle load!) and most links on the 1st page of the result leads to NRDC page. Also, the user who created it has been blocked! I do sense Neologism μTalk 22:25, 1 September 2017 (UTC)

If this was the same topic as standby power then the right action would be delete, redirect, or merge. However, the article makes a distinction with stanby power right at the beginning of the lead. If I understand this correctly, the idle load is the power used by the home when the home user isn't doing anything. For instance, the fridge will come on by itself if its internal temperature rises. The home user didn't intervene for this to happen, but it is definitely not standby power. This is to be compared with the home user getting out the vacuum cleaner for instance. I don't think we should get too hung up on whether or not home idle load is a neoligism; the article title can be changed if necessary. The real question is whether this is a real topic or not. On that I'm not so sure. Domestic energy consumption is certainly a big environmental and economic issue nowadays, but I'm far from convinced that anyone is making a big distinction between fridges and vacuum cleaners. The only point to home idle load, as far as I can see, is that the data can easily be extracted from smart meters whereas standby power cannot. SpinningSpark 10:37, 2 September 2017 (UTC)

It does appear to be mostly an NDRC thing but it looks like other organizations have picked it up. The article is integrated well with other articles in the topic area. I'm not inclined to propose a merge or nominate for deletion. ~Kvng (talk) 15:10, 5 September 2017 (UTC)

Proposed deletion of Linda Shapiro

The article Linda Shapiro has been proposed for deletion because of the following concern:

I don't believe that Professor Shapiro meets the basic notability guideline, of having "received significant coverage in reliable sources that are independent of the subject." I looked through the top 50 G-Hits for "professor Linda Shapiro" and quickly realized that there are multiple subjects, found no independent reliable sources providing coverage, and got to the point where the three words were each appearing separately in the article instead of together.

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist.

WikiProject collaboration notice from the Portals WikiProject

The reason I am contacting you is because there are one or more portals that fall under this subject, and the Portals WikiProject is currently undertaking a major drive to automate portals that may affect them.

Portals are being redesigned.

The new design features are being applied to existing portals.

At present, we are gearing up for a maintenance pass of portals in which the introduction section will be upgraded to no longer need a subpage. In place of static copied and pasted excerpts will be self-updating excerpts displayed through selective transclusion, using the template {{Transclude lead excerpt}}.

The discussion about this can be found here.

Maintainers of specific portals are encouraged to sign up as project members here, noting the portals they maintain, so that those portals are skipped by the maintenance pass. Currently, we are interested in upgrading neglected and abandoned portals. There will be opportunity for maintained portals to opt-in later, or the portal maintainers can handle upgrading (the portals they maintain) personally at any time.

Background

On April 8th, 2018, an RfC ("Request for comment") proposal was made to eliminate all portals and the portal namespace. On April 17th, the Portals WikiProject was rebooted to handle the revitalization of the portal system. On May 12th, the RfC was closed with the result to keep portals, by a margin of about 2 to 1 in favor of keeping portals.

There's an article in the current edition of the Signpost interviewing project members about the RfC and the Portals WikiProject.

Since the reboot, the Portals WikiProject has been busy building tools and components to upgrade portals.

So far, 84 editors have joined.

If you would like to keep abreast of what is happening with portals, see the newsletter archive.

If you have any questions about what is happening with portals or the Portals WikiProject, please post them on the WikiProject's talk page.

Thank you.    — The Transhumanist   10:55, 31 May 2018 (UTC)

Greeting fellow collaborators. I went looking for an article on three phase transformers and found none. I hope to encourage someone who knows to add content to the transformer article or create a new article. I am particularly interested in whether the voltage ratio is the same as the turns ratio.

Many pages currently link to Conductive, which redirects to Electrical conductor. I wonder whether it ought to redirect to Electrical resistivity and conductivity, which is a separate article. Michael Hardy (talk) 15:24, 13 May 2019 (UTC)

I would be cautious of changing a redirect target that has been around for so long (since 2004). The individual usages have to be examined on a case-by-case basis to see if this makes sense. While some of them could arguably be referring to either a physical conductor or the property of conductivity, in many cases the author clearly intended to link to the conductor article. Transmission medium even links to both pages in the same sentence contiguously. It is beyond argument in that example that the author intended the link to go to the electrical conductor page.

Locked Rotor Test / Blocked Rotor Test

https://en.wikipedia.org/wiki/Blocked_rotor_test "It is also known as short circuit test, locked rotor test or stalled torque test.[1] " to be REMOVED

This article on Wikipedia states that it is also known as short circuit test. I think this is wrong because a short circuit test would literally mean there is a short circuit within the induction motor.

They are two separate types of circuit analysis. A Locked Rotor Test is like a motor that simply operates like a transformer or a simply inductive load, because the "rotor is locked". Where as a short circuit test is a literal short due to failure.

Can someone remove the term "Short Circuit Test" from the Locked Rotor Test article. It has caused massive confusion to the electrical community.

Further when we look at motor datasheets by manufacturers they state Full Load Current (FLC), LRC (Locked Rotor Current) and SC (Starting Current). Confusion occurs when the datasheet states SC current. So for a 37kW motor star-delta start, this could be FLC = 64A and SC = 179A. The SC acronym can get confused with "Short Circuit".

Therefore I suggest "It is also known as short circuit test, locked rotor test or stalled torque test.[1] " is removed — Preceding unsigned comment added by 82.46.189.149 (talk) 08:15, 26 May 2020 (UTC)

Hi Robert. A big problem is that all your references are commercial websites with advertising. Constant314 (talk) 23:35, 1 June 2020 (UTC)

Well the editor addressed the only specific actionable comment left by the first reviewer and replaced the source. There might still be some issues with sourcing, but AFC review shouldn't be trying to get the sourcing perfect. The rule should be (but often isn't with many reviewers) that if the article would pass an AFD then it should be posted to mainspace. I don't see any major difficulty with this one, it's going to pass the notability test and it's not making any dubious or promotional claims. You might have to bite your tongue sometimes, but we shouldn't make new editors jump through hoops. It's very discouraging to make the changes requested and then have it rejected again.

We already have a Capacitive stylus redirect and I have adjusted it to point to Stylus (computing)#Capacitive stylus and left a message on Talk:Stylus (computing) about Draft:Capacitive stylus. ~Kvng (talk) 13:19, 4 June 2020 (UTC)

Missing section or article: (extra-)low-voltage wiring, from more than a technical perspective

We don't seem to have an article or section on general-interest information on what "[extra-]low-voltage wiring/cabling" generally refers to, only technical and spec information from the engineering side, at Low voltage and Extra-low voltage, both of which are basically stubs that address only a few countries. I've added an entry, "* Voice, data, and video" to the VDV disambiguation page, but there is no article or section to which to refer readers, other than Extra-low voltage, which does not address various classes of and occupational specialties in low-voltage electrical cabling (and there are others, like home theatre and audiophile, and high-precision scientific and industrial). Similarly, there is nowhere to point redirects like Voice, data, and video; Voice, data and video; Voice, data & video; Voice-data-video; Voice–data–video; Voice/data/video; Voice data video; Video, data, and voice; Video, data and voice; Video, data & voice, Video, data, voice; Video-data-voice; Video–data–voice; Video/data/voice; Video data voice.

I would think that somewhere there's already info on WP about audophile and home theatre cabling, but all of this stuff should get WP:SUMMARY treatment at Extra-low voltage or at Low voltage (whichever seems most appropriate), in sections particular to well-defined general classes of use. And we need better cross-referencing between Low voltage and Extra-low voltage; when people who are not specialists use "low-voltage" (or "low-power" or "low-current") they are usually thinking of what is technically/legally more often classified as extra-low voltage (a term which is not in general usage among the public, only among specialists). So, they are apt to arrive at Low-voltage which [in its present stubby state] may not be really what they're looking for.

Some other content that should get in there is worker licensing/classification. E.g., one does not have to be an electrician or otherwise professionally certified to work on extra-low voltage installations (in most jurisdictions), but some classes of "low-voltage" will get into certification/licensure-required ranges in some places. Similarly, building codes are going to have requirements for some things that are technically "low"-voltage, but most often not when it comes to extra-low voltage. Basically, if it can cause a fire, or cause a burn or pacemaker failure to a human, or something like that, there's a higher chance a jurisdiction will impose some restrictions. All of this is encyclopedic information to have somewhere, but all we've got right now in the obvious places are a handful of technical/mathematical and national-specification notes.  — SMcCandlish ☏ ¢ 😼  03:24, 4 August 2020 (UTC); revised 06:42, 4 August 2020 (UTC)

I've never heard of extra-low voltage wiring, but looking at the article, it seems to be about power-supply voltages, not about audio and video signals. Is your point that consumer AV equipment is often powered from the same cables that carry signals? Or just that audio and video signal are at quite low voltages? The ELV limit of 50V sounds like what I'd call low voltage (like in 24 V landscape lighting), and high compared to what I'd expect in AV equipment. The standards are weird. Dicklyon (talk) 04:25, 4 August 2020 (UTC)

It's more that "low voltage" is a general term with broad application to anyone into electronics in general, systems and network administration, point-of-sale systems, security cameras, gamer PC modding, 3D printers, CNC controllers, drones and RC models, AV equipment, ham radio antennas, coax and cable modems, etc., etc. It basically means "everything that probably can't fry you or burn the building down", i.e., stuff it's legal and generally safe to work on without being an electrician.  — SMcCandlish ☏ ¢ 😼  06:39, 4 August 2020 (UTC)

Interesting questions. The article about extra-low voltage is aimed at component-level engineers, not consumers, which is how it should remain. The low voltage article is the more general interest topic; it could be expanded to include a list of common applications such as wired remote controls, doorbells, building alarm wiring (Electromagnetic lock etc.), various video formats (Serial digital video, etc.) and audio formats (Intercom, Line level analog audio, etc). Binksternet (talk) 04:51, 4 August 2020 (UTC)

That sounds reasonable to me.  — SMcCandlish ☏ ¢ 😼  06:39, 4 August 2020 (UTC)

Low voltage and extra low voltage are specific terms used in electrical power distribution applications. The existing articles should not have information on audio and video coatracked on to them; articles are supposed to be on a single topic. Low voltage has no specific definition in audio or video, and when used generically in those fields is likely to have a radically different meaning – 500 volts would not be considered low voltage in audio, but it is within the power distribution definition. Basically, it is voltages that might be supplied to consumers as opposed to high voltages (1kV+) found on transmission lines. Extra low voltage was defined because voltages safe to use in bathrooms etc were required. I'm not convinced that a low-voltage audio or video article is viable. Is there such a thing as high-voltage video to contrast it with? Are there some general statements about low-voltage wiring that could be made? We do have an article HT (vacuum tube) covering high voltages in old TVs, but that is a specific application and its hard to see how a low-voltage article could be focused and not become a useless rambling list of everything consumer. SpinningSpark 14:33, 4 August 2020 (UTC)

Good point. No need to mess up power distribution context with signal-related trivia. It's clear than +4 dBu is higher than -10 dBv, but it has not place in power-related articles. Retired electrician (talk) 18:23, 4 August 2020 (UTC)

We do already have Audio and video interfaces and connectors for AV wiring and connectors. ~Kvng (talk) 21:18, 6 August 2020 (UTC)

Makes me wonder if EmPower (aircraft power adapter) and USB Power Delivery and Wall warts belong in Extra-low. !!!!

Edit war on Electric field

Edit war on electrocution

Regarding the inclusion of 'severe injury' in the definition of 'electrocution', this appears to be from both the Merriam-Webster and Oxford dictionaries perpetuating this misuse of the term. Many attempts have been made to correct the Wikipedia definition - but a couple of people refuse to accept sources other than those 2 listed above.

The CDC, OSHA, CCOHS - all make the distinction that "Electrocution results when a human is exposed to a LETHAL amount of electrical energy", leaving no room for injury alone.

https://www.cdc.gov/niosh/docs/98-131/pdfs/98-131.pdf?id=10.26616/NIOSHPUB98131 - top of page 6 https://www.osha.gov/dte/outreach/construction/focus_four/electrocution/electr_ig.pdf - Content for Topic 1: A. Definition https://www.ccohs.ca/oshanswers/safety_haz/electrical.html - What kinds of injuries result from electrical currents?

This is also the distinction as exercised in the legal and medical professions, though citing direct sources has been difficult to come by. If the current Wikipedia definition is to be supported - how do you distinguish between 'shock' and 'electrocution'? — Preceding unsigned comment added by N8skow (talk • contribs) 14:47, 31 August 2020 (UTC)

Requesting a look at Hydroelectric cell

Hydroelectric cell is a type of fuel cell or similar that appears to be misrepresented in the article as 'a primary source of green energy' and an alternative to a solar cell.

The article makes claims such as "Hydroelectric cell different versions have been reported to produce green electricity using water droplets only." and "Recent studies confirm that Hydroelectric Cell generates green electricity by splitting of water only and is an alternative to Solar Cell and Fuel cell". This makes it sound like this technology is the equivalent of a photovoltaic cell, a "hydro-voltaic cell" if you will, which I don't believe is accurate.

The article also makes statements such as "Hydroelectric Cell working is a unique device based on the combination of material property, oxygen deficiency, Nano science and electro-chemistry." This sounds to me like an exceptionally vague string of jargon and buzz words that doesn't have much meaning once you drill down.

The article also gets rather promotional in the 'performance', 'advantages', and 'usage' sections and was created and heavily edited by a few SPAs that appear to have a COI, making me more suspicious.

Without sufficient familiarity with the topic or expertise in the field, I don't know if this needs minor editing, major editing, or deletion.

Thank you! Paisarepa 18:20, 15 September 2020 (UTC)

From the article it appears that the energy comes from oxidizing zinc to zinc oxide.   That would make it an alternative to a primary chemical cell rather than a fuel cell or a solar cell. I guess the greenness depends on how greenly you can get unoxidized zinc. Constant314 (talk) 19:52, 15 September 2020 (UTC)

Constant314 Zinc > zinc oxide cells have been widely used to power hearing aids for a very long time. See Zinc–air battery -- Roger (Dodger67) (talk) 21:33, 15 September 2020 (UTC)

I wasn't suggesting that there was anything suspicious. In fact, I meant the opposite, that is that there was a plausible chemical energy source. In other words, it is not a free energy source. Constant314 (talk) 22:06, 15 September 2020 (UTC)

They've been published in a number of different journals now, but I'm not seeing any counter-articles. I think we should be hesitant about declaring this a hoax until we have some sources saying it's bollocks. For now, just concentrate on cleaning up the POV.

A History of the Theories of Aether and Electricity

Hi all, I created a new article A History of the Theories of Aether and Electricity and filled in much content. I was very surprised the article did not exist before as I had already knew of it from my graduate studies in physics. I have already posted on the physics WikiProject talk page inviting them to edit the page and it got some help. In the course of filling out the page, I noticed it is used by engineers as well, so I also wanted to extend the invitation here as well. Thanks!Footlessmouse (talk) 01:03, 2 October 2020 (UTC)

Contact Resistivity and Circular Transmission Line Method

I have written a six page Word document with equations, tables, and figures on the above subject area. I believe my article is within the wikipedia guidelines. For a brief time period at JPL I was quite knowledgeable about contact resistance. I have no propriety interest in the article, all of my work was previously submitted and published in journals or conference abstracts. I would like someone to review my efforts and enter it into the encyclopedia because the present contact resistance article is limited in scope. Dale R Burger (talk) 05:56, 4 November 2020 (UTC)

High-voltage transmission line Kassø-Tjele

Hi. I translated Draft:High-voltage transmission line Kassø-Tjele from Danish Wikipedia. I would appreciate if anyone would check that I got all the technical terms translated correctly, and that the article language usage is generally in order. Feel free to ask if anything needs clarification. Thank you for your help! --Dipsacus fullonum (talk) 18:52, 24 September 2021 (UTC)

That looks good to me. Because it is a technical topic and relies on foreign sources I predict it will take a long time to get this declined at WP:AFC. You're probably better off moving it to mainspace directly. It is definitely in good enough shape for that. I will watchlist this draft and help out as needed however you choose to introduce it. ~Kvng (talk) 20:28, 27 September 2021 (UTC)

No need to wait for AFC, it doesn't have an AFC template in any case. I've moved it into mainspace. I've changed the title to Kassø-Tjele high-voltage transmission line to be more in line with usual English grammar. SpinningSpark 20:56, 27 September 2021 (UTC)

Pellegrini Articles

While reviewing the "articles needing attention" over in Wikiproject Physics, I ran across two which... might be more in this project's wheelhouse? Or they might be WP:FRINGE, I'm genuinely not sure. They certainly don't seem to have a lot of secondary coverage. Can someone here voice an opinion as to whether these two articles should be cleaned up, pared down, or nominated for deletion?

• Cut-insertion theorem
• Electrokinematics theorem

Thanks for any comments. PianoDan (talk) 23:37, 7 December 2021 (UTC)

• Both articles are primary sourced to books and articles by Bruno Pellegrini (and his close associates), both promote the author, and both seem to have been created by the same WP:SPA. The only secondary source with significant coverage that I could find for Cut-insertion theorem is quite critical of that approach.[4]. The papers are not well cited (they are mostly cross-cited); the theorems do not appear to have caught on, and don't appear to be notable. SailingInABathTub (talk) 01:18, 8 December 2021 (UTC)
• I was about to say much the same thing. This is self-promotion either by Pellegrini himself, or more likely one of his students. The first article is entirely based on primary sources, and the second one only has sources not associated with Pellegrini for statements on the work of historical figures. I also note that Pellegrini has been given an redlinked entry in List of people in systems and control. I think that page needs looking at as well. There are an awful lot of redlinks. The page shouldn't be a list of everyone who has ever written a control theory paper. SpinningSpark 11:20, 8 December 2021 (UTC)

I spotted that one too - I've done a first pass clean-up to remove the non-notable entries. SailingInABathTub (talk) 11:59, 8 December 2021 (UTC)

• OK, thanks for the sanity check. I'll go ahead and start AfD. PianoDan (talk) 17:11, 8 December 2021 (UTC)

I don't think they are FRINGE though, not in the sense that they are promoting something that no one else believes. They are just not all that important in network analysis or control theory as far as I can tell. SpinningSpark 17:33, 8 December 2021 (UTC)

That seems reasonable. I'm not knowledgeable enough in the specific areas to make that determination, so I didn't mention the possibility on the AfD pages. PianoDan (talk) 17:46, 8 December 2021 (UTC)

Recent version of IEC 61000 series standards

Hi all,

I'm wondering about the actual version in some IEC 61000... articles. E.g. "The current version is Third Edition dated 2014-05-15" (of the IEC 61000-4-5). It is still valid, of course, but there is a more recent version with the Amendment 1 of 2017 (see [5], for valid versions have a look at ""Additional information" / Historie for the current / valid versions). Are the "major releases" the only one that should appear? Or is the article (and some other) simply outdated? The latest edits are from 2020, a long time after the release of the AMD 1:2017. 80.79.86.132 (talk) 08:04, 2 February 2022 (UTC)

Statements like "The current version is..." date quickly. Best to use {{As of}} or remove completely, if possible. A lot of maitenance edits may occur but this doesn't mean that anyone has recently intelligently reviewed the content of the articles. ~Kvng (talk) 15:46, 5 February 2022 (UTC)
