Jbartos,
Let me give you an example of a query of the type I'm characterizing, i.e., one lacking sufficient detail:
A pumping station consists of two generators, A&B. They serve a 480 V substation supplying power to 4 pumps.
Gen A is 5kV, 680 kVA, 0.8pf. Gen B is 480V, 1000kW, 0.8pf. Each of the pumps is 300Hp.
The problem is that every time the generators operate in parallel, the Gen B incomer trips on ground-fault.
What's wrong?
Oh, I forgot, there is also a utility tie.
Also, Gen A is connected via a stepdown transformer.
Furthermore, the pump motors are equipped with VFD's, etc.
One is painted green the others aren't.
Now, I understand the principle of asking probing question... I also teach "Problem Solving" techniques to students in a post-secondary school.
My, point is that the info presented is so sparse as to take a lot of time eliciting meaningful data.
You, yourself, in an earlier forum, expressed disdain at the incompleteness of info, albeit, perhaps not as pointed as my suggestion is. We older, and I apologize if my characterization of you is in error, should be providing knowhow, and techniques, commensurate with our professional experience.
That's all I meant by this forum. It was not intended to embarass anyone, nor step on fragile toes.
