Understanding three phase.

[Rampage]

I've heard many a time on here that people don't understand three phase enough to work on it.
Im just wondering what exactly people don't understand?

Rampage ,
after 3 pages of posts youre still trying to blag us that you have comprehensive understanding of multi-phase distribution that you have learnt from your domestic installers course.
just give it up , your fooling no-one.

Why are we talking about 6 and 12 phase, you’ll never come across it.

You definitely don’t understand the maths or physics of them.

I asked about a four phase model to ascertain his understanding of the maths (and corresponding physics), that's what he was replying to.

Yawn yawn yawn snore snore Zzzzzzzzzzzzz

if i had 10% of tony's knowledge on 3 phase and HV, i'd be ecstatic.

i'd rather have 10% of his wages.

Sorry to bore you.

Second that!

To the OP, I shall try and repeat the same but more tactfully

After 3 weeks on a DI course, you will have been given a short overview of what a three phase system is and how it functions, hell you could probably open up a TP board and confidently add a circuit, but that's about it. Competence is key here and there is no way you could ever explain to a court should any of your work go wrong on a TP system that you are in any way competent to be doing what you're doing (assuming you are working on TP systems).

I'm sure most DI's understand the basics of three phase distribution, or at least recognise what it is, however most won't touch it for one of two reasons, 1; they're either not insured to work on TP, and/or 2; they don't know enough about it to deem themselves competent to work on it.

My strong advice would be to get yourself to college and enroll on the 2330, or if you can the 2357. The knowledge gained at college, although not perfect, will at least stand you in good stead for any future potential employers instead of the electrical trainee qual you have at the moment which will get you nowhere in the industry. If you're concerned about not being able to enroll, there are plenty of colleges nationwide that offer both day and night time courses, so IMHO, there's no excuse not to go! You seem like a chap who's keen to learn, but maybe if you reign in the slightly overinflated ego and realise that you still have a lot to learn, you'll realise that there are plenty of good guys out there who will be willing to teach you!

This thread is up to 4 pages and 52 replies, and we haven't even scrapped the surface of understanding 3 phase, let alone 3 phase installations...

As most experienced electricians have already stated, your not going to know much at all with just an overview of training from one of these fast track courses. Too give you just a bit of an idea, I rarely think in single phase terms, it's only when you get right down the line to the final circuits, that single phase appears on my projects. Even then, those final circuit DB's will invariably be 3 phase arrangements, there maybe one to three single phase DB's on the whole project. There is a vast amount of 3 phase MV and LV distribution before you get that far down the line though...lol!!!

Says a lot for having a domestic and commercial electrician grades

Sorry to bore you.

Sorry BUT
Im looking at this thread and wtf if you don't get it or understand it go back and retrain don't attempt to open a tp&n board, if your a 3,5wwder and got domestic installer & you have fluked your way through stick to domestic work

I think we should all have a grasp of both sides of the domestic / industrial divide. It’s when people try to use that limited knowledge outside their usual field I get worried. Like E54 it was unusual for me to get involved with sub-circuits but I needed a full understanding of them. Again like E54 the last plant I worked on you could count the number of single-phase boards on the fingers of one hand.

I had hoped this thread would lead to something useful before it got out of hand. I do like being put on the spot with questions, it helps me take my mind off other things.

So you've looked at this thread and decided that I don't understand three phase and am a Electrical Trainee?

Well I was trying to help, I shan't bother again.

There's a spark and a proper spark the proper spark can turn his hand and knowledge to whatever is required to do a job and the spark will watch in amazement Lol

Ok clever clogs! I'll put you on the spot with a question even you can't answer.....
