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. (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. ShriRamTalk tome 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. -- (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! ShriRamTalk tome 18:37, 16 June 2012 (UTC)
Sure, no problem. Whenever you have time, or someone else joins who has an account. (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. -- (talk) 18:52, 16 June 2012 (UTC)

How about a shortcut to the banner? WP:WPEENG -- (talk) 22:07, 19 June 2012 (UTC)

Hi (or which other IP you are now using), Is it ok to delete the banner pages? Since we have now the {{WikiProject Electrical engineering}} template, it is unlikely that it will be used in the future. Kind Regards, SchreyP (messages) 16:56, 13 July 2012 (UTC)


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

EE, Eengg, ele engg would be fine. do you think double is req? ShriRamTalk tome 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. (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)

Synchronous motor[edit]

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)

Currently editing it. ShriRamTalk tome 07:56, 9 January 2013 (UTC)
I hope now there are enough number of references to support the contents. If you find anything odd, do leave a note on the article's talk page or here. We will see what we can do. Thanks for the note. ShriRamTalk tome 07:33, 19 January 2013 (UTC)

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 (talk) 21:14, 7 June 2013 (UTC)

Hello again electrical experts. Here's another of those old drafts about to be deleted. Is there anything worth keeping? —Anne Delong (talk) 21:33, 8 February 2014 (UTC)

Some of the content in the Wikipedia_talk:Articles_for_creation/ETAP#Need_for_Power_Systems_Analysis section may be useful to Electric power system, Fault (power engineering) or Power-flow study. Would be more useful if there were footnotes. ~KvnG 13:24, 12 February 2014 (UTC)
Well, since you don't indicate that it is a worthwhile as a stand-alone article, I won't postpone its deletion now. If anyone does want to move a section to another article, any edit will postpone the deletion long enough to do the work, and then we can change this one into a redirect to maintain the attribution. —Anne Delong (talk) 20:04, 12 February 2014 (UTC)

Another AfC submission - Rotating Armature Alternator[edit]

The AfC submission Wikipedia talk:Articles for creation/Rotating Armature Alternator seems to be about a specific historical powerhouse. Please could you offer opinions on whether this submission is useable as the basis of a mainspace article.

Comment on the WikiProject X proposal[edit]

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! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

Donation of images for electromagnetism articles[edit]

Simulated electric field around a printed inverted-F antenna.[1]
Multipaction within the gap inside a coaxial connector, driven by fields between the conductors. Color represents electron energy[2]

(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.

WikiProject X is live![edit]

WikiProject X icon.svg

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[edit]

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.
- The electrostatic potential that applies to electrostatics and DC circuits or any situation where σA/σt = 0. In this case, the difference in potential between two points is the same as the voltage between those two points and EMF evaluated along any path is also equal to the same voltage.

Qualcomm Snapdragon[edit]

I have shared a draft on the Talk page of the Qualcomm Snapdragon article here. The current article is sort of a mess and this is my attempt to clean it up and get something encyclopedic in place. I'm sharing the proposed re-write on the Talk page, since I have a COI/financial connection with Qualcomm. I thought I would drop a note here in case anyone from WikiProject Electrical Engineering has some familiarity with the subject and may have an interest. It is a system-on-chip product used in most Android phones. CorporateM (Talk) 00:19, 23 June 2015 (UTC)

Rotating electrical machine articles need some attention.[edit]

  • 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)
Did some cleanup at armature. I'm trying to make at least the lede sections comprehensible to non-EEs. John Nagle (talk) 20:50, 2 January 2016 (UTC)

I've added all related articles to Wikipedia:WikiProject Electrical engineering and have done some cleanup. ~Kvng (talk) 19:31, 5 January 2016 (UTC)

Proposed deletion of Singly-fed electric machine, on the grounds that nobody uses that term, except in a few articles about doubly-fed machines. The article has lacked references for 10 years. If anyone wants to remove the "prod", go ahead, but fix the article if you do, and write a comprehensible lede sentence. Thanks. John Nagle (talk) 21:46, 5 January 2016 (UTC)
I have cancelled your WP:PROD: "We don't delete awful articles, we improve them. If you think the subject is only notable in the context of doubly-fed electric machine, I suggest you propose a merge to Doubly-fed electric machine." I will try to improve the lead and add some refs. ~Kvng (talk) 15:48, 9 January 2016 (UTC)
OK, rewrote singly-fed machine as just a definition, leading to motor and generator for details. John Nagle (talk) 21:16, 17 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).") Help. John Nagle (talk) 21:16, 17 January 2016 (UTC)
I agree that it is very difficult to read, but it is not worthless, so I wouldn't support deleting the article. On the other hand, if it was machine translated from copyrighted material, I believe the copyright survives the translation.Constant314 (talk) 03:04, 18 January 2016 (UTC)
I don't think it was machine-translated; that editor just writes that way. I'm taking a shot at fixing it here: User:Nagle/sandbox/doublyfedintro. John Nagle (talk) 03:38, 18 January 2016 (UTC)

balanced fault <> symmetrical fault[edit]

Hello, I was reading [(power_engineering)] page. It say that a balanced fault is a synonym for a symmetrical fault. But according this article, it's not. — Preceding unsigned comment added by 2A02:A03F:4E1:6F00:A158:E9F8:76B8:4BF1 (talk) 08:19, 13 July 2016 (UTC)

Project overlap[edit]

How is this project different from Wikipedia:WikiProject Electronics? ~KvnG 15:39, 25 January 2014 (UTC)

Outline of electrical engineering has electronics as a sub field of electrical engineering. I don't agree with some of the divisions--signal processing and control theory have a big overlap with electronics, for instance. But I have always thought of large scale electrical power generation and distribution as something outside of electronics and in EE. --Mark viking (talk) 18:37, 25 January 2014 (UTC)
So any article in WP:ELECTRONICS should also be in this project? ~KvnG 14:54, 30 January 2014 (UTC)
Kvng No, that would not be ideal. Electrical engineering excludes most concepts in the broader field of electronics. Electrical engineering is its own concept. Blue Rasberry (talk) 20:02, 25 February 2014 (UTC)
Does someone want to take a stab a clarifying the project's scope? Here's what's currently said, "The project generally considers any article related to Electrical engineering to be within its scope." ~KvnG 20:22, 25 February 2014 (UTC)
Perhaps the voltage used should be the dividing line? Electrical Projects dealing with voltages of at least [whatever] Volt, while Electronics Projects work with voltages below that. (talk) 04:14, 23 July 2016 (UTC)
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. Electrical engineering also covers both signaling and power applications of electricity. I really can't think of a clean way to differentiate these and I think the projects should be merged. ~Kvng (talk) 15:30, 26 July 2016 (UTC)
I think anything about circuit design and function is electrical engineering. Articles about specific electronic products, such as the iPhone and its success might be in electronics but not in electrical engineering.Constant314 (talk) 18:50, 26 July 2016 (UTC)
