A question from a mate

[Darkwood]

Ok thanks, if its too much to delete somebody could DM me?

Will do ... probably evening before Marvo is back so he can repost it, its to do with 3ph balanced loads with common connection in star formation not requiring a N, you would only get a N current if the loads were out of balance if you want to look into it in the mean time.

This is one way to work it out. As L1 L2 L3 will all be the same then the neutral current will be zero.

Im=√((IL1-0.5(IL2+IL3))²+(0.866(IL2-IL3))²

I have undeleted it now so it should be viewable if you click on it, I just hope I don't get in trouble with Trev or Marvo, If I do I'll blame Paulm if he's not online :yesnod:

Funny :rofl: doing a bit of learning myself at the moment mate, hence not being logged on that much these days.

ps, I'm sure Trev will be fine with it? If not, your in a bit of bother bud!

 

[trev]

Trev is fine with it.
The answer was wrong btw. I too was wrong but not as wrong as the answer given. I'll ask for the worked example tomorrow.

 

[Marvo]

I should really fix the sketch but I'll just give a warning that the colours I used are not the harmonised wiring colours we should all be using. Old habits die hard.

You lost me there .... I'm intrigued now, it's a typical 3ph star arrangement so no neutral required unless the neutral switching isn't as we perceived ... :shocked:

thanks mate having a look into that now

Right, I was given some drawings today and I've dropped a complete b0llock with how I've posted this up. So I'm going to draw it out and take a photo of it, take a photo of it then post it up.
Bear with me ladies n gentlemen.
