Cr4p I Find on the Internet

02/17/2012 3:38 PM

From GardenWeb.com's Home Electrical Wiring section:

"I'm trying to understand those wires in my house (I haven't been paying attention in school :-) and I have one question: where does the neutral wire come from? My understanding that the power company only supplies the hot wires, and the neutral is tied to the ground wire at the main service panel, but looking at the diagram below there's a white neutral coming in."

Response from an astute "electrician":

"The neutral wire is the return path for the spent electrons to return to the transformer for re-energizing. The neutral completes the path so that the transformer can keep functioning. There are two types of power distribution: Wye and Delta. Wye, more common and newer, uses 3 phases plus a neutral conductor. The neutral is grounded both at the substation and at every power pole. Delta uses 3 phases and no neutral. In Delta there is only a single voltage, between two phases (phase to phase), while in Wye there are two voltages, between two phases and between a phase and neutral (phase to neutral). For further reading do a Google search on AC power generation and distribution."

Wow...

That sounds like an "e-how" presentation.

e how is the most useless thing on the internet!

Here's an example.

How to change a tire:

Jack the car up where the tire needs replacing.

Use the car jack to jack the car up.

Place the jack underneath a solid, fixed place underneath the car (like part of the frame). Don't try jacking the car up underneath the muffler or axle because it will damage the car.

I think the big question here, is what the H-E double hockey sticks were you doing on e-how, looking up how to jack up a car.

It was a subject I chose at random because most of us understand how to change a tire. Imagine, if you had no experience with a car and this was your only source of information. It's an insult to even semi-intelligent people.

Besides, I don't change tires any more, we have Triple A.

Yeah, I've ended up on ehow when looking for something. Haven't found one topic description that isn't worthless.

"It's an insult to even semi-intelligent people."

But don't forget, only a small portion of the world population is even "semi-intelligent".

I once submitted a piece to ehow and it was shot down as unworthy.

I don't think so. It was probably too simple.

I had water seepage on one corner of my basement when it rained. It was down low and I didn't feel like digging out the exterior wall. I figured if I dumped the ash from my wood stove around that outside corner, the rain would carry it into the ground and eventually stop the leak..............................it worked.

This was the "wow factor" for me...

"..return path for the spent electrons to return to the transformer for re-energizing"

The rest of it is superfluos drivel unrealted to the context of the question, but that first statement was, well, just... wow...

I have read a few pretty ridiculous responses here at CR4. I sort of remember reading in this forum somewhere about those spent electrons being recharged.

I recently read an editorial about the threats to the Internet. One thing the columnist missed was that the Internet is becoming overwhelmed with superfluous content. Mostly useless, but some down-right dangerous. When was the last time you did a search for which the first two or three pages weren't filled with some marketing promotion by representatives of Chinese vendors??? Try a search with "energy" in your string- most likely, you will have a minimum of five pages of over-unity hits before you find anything real. The loudest voices get the attention- and, generally, those who scream loudest have less evidence to support their position. If you don't already know where to look for the information you are seeking, it is getting harder and harder to find it...

Also, most is not dated as to original entry or update actions along with insufficient/no documentation or substantiation. As always "buyer beware".

The electrician's answer isn't so dumb, actually. The 'spent electrons getting reenergized' sounded way out at first, but when you think of it that's exactly what happens.

Energetic electrons at the live transformer terminals flow through loads that drain their potential energy and transform it into heat or work. The electrons, depleted of some of their potential energy (for a given electron, voltage drop times its charge), go back to the transformer, through which they flow and have their potential energy restored.

Thus, electrons DO get reenergized. Work is done on them in the transformers, which raise their potential energy.

Maybe, but the OP has no business even thinking about messing with the wires in his house, and for all practical purposes, the answer could have been a description of steam turbine electrical generation. I doubt the OP came away knowing what the "white" wire really does.

I hope you don't mean me OP and meant GardenWeb OP...

One additional part that anyone failed to mention was the connection points to delta and wye and how one derives voltages from the phases...I found that quite interesting

As to the "travelling" of electrons to and fro...we're talking AC here...the "movement" of electrons isn't creating electricity. Electrons do not lose their charge. If an electron needed re-energizing it wouldn't be an electron anymore. One also cannot change the speed of electron "movement" (~.01 cm/minute) by pumping up the voltage...if we could do that then we could change the speed of light by varying color temperature...oops...wait...what color were those electrons? Are they red-shifted?

Yes, the garden web OP.

Hmmm, I've got an electrical question..................I think I'll go find a gardening site to find the answer.

According to Dave Barry, most folks don't examine their electrons closely and the power companies have been reselling us the same electrons for years!

And then all those who get killed while they pay the bills.

I'm the one that will not go near the whole department. It's a dangerous hobby and should only be carried out under strict supervision, if at all carried out by the handy man. Gosh I hate that twitching sensation.

Coming to think of it any of the major trades have their danger zones. All our collective scars are proof of that and many of them could have had worse outcomes, at least mine.

Picking up a trade by watching Utube could have very serious consequences. Recognizing hints and specialties can be very enjoyable for the knowledgeable, learned observer though. Outlawing stupidity?...............

Darwin's 'Theory' and Murphy (I'll get you one day) will be in charge, whatever our business.

*usually 50 or 60 times every second. Just how much is an electron really worth, I wonder?

You ought to publish the name of the electrician, I would not have him any where near to my house. Nor should anyone else either.....

Also anyone who somehow reads any sense in his words is as misinformed as he is.....

The comment was completely and utterly wrong, but that is the state of training of some electrical people around the world....I have met them time and time again, some on CR4.....sadly.

To answer the OP, either a neutral is supplied by the service company, or one is made locally "in house" in one of several possible ways depending where you are and local code.

The main rule is that the neutral to ground link may only be made once.....local codes apply.

Then there's the single wire earth return (SWER) systems that you find way out in the bush.
