Hi GITRDUN
I would not accept that, not a chance in hell. It is not a genuine 3-phase Y connection. Frankly, I think it is a cheap fudge or fake which will cost the PoCo virtually nothing. All they would do is switch a few wires around, nothing more. It will not solve your problems (your machines being damaged) either.Ok so some progress maybe. I talked with the city electrician to see about having them switch my transformers over from 3-phase high leg delta to a 3-phase Y. Right now i have three legs at 120V 120V and 208V and all are 240V phase to phase. With the Y setup i will get 120V 120V and 208V but all will be 208V phase to phase. Is this correct?
What you want is a genuine 4-wire 3-phase Y connection with the same voltage on all three phases, using a genuine 3-phase transformer. NOT some bodgy antique Heath-Robinson high-leg delta lashup from 100 years ago. This is what the rest of the world runs with, and what much of America gets as well. Do not compromise on this, do not let them cheat you. Yes, this means they will have to suffer the horrrible expense of actually buying a new 3-phase transformer. Oh, the suffering, the anguish at their bottom line, the paperwork. Tough: you have paid your power bills for years and been served with crap power which has cost you huge amounts of money and frustration. Time for a change.
You now have them admitting there is a problem. They are trying to negotiate the cheapest solution they can get away with - at your expense. Naturally, their opening offer costs them nothing. Nihil illegitimum carborundem!
Cheers
