Hi Waross, Thank's for your interest. PRJM

Thank's. I have to go too. I'll come back some time tonight. PRJM

Hi Waross 1&2> The three 100 KVA or not identical, not from the same manufacture. Can it cause mismatch? I don’t have exact 600v voltage reading phase to phase on the padmount secondary when hydro plant is running. 3 to 4 volts difference. 3> Third harmonics! Tell me more about them. My...

Hi Waross, After I read what you wrote “against” delta-wye systems, I was sort of confused, though you might have described part of my problems. Over the years I raised the voltage on my power line 2 times. Once from 2.4kv D-D to 7.2KV D-D. 3 years ago I raised it again, to 12.4KV this time...

Hi Waross, Thank's for the answer. I was affraid I was right. I'm preparing another question for you. I will post it sometime tonight. PRJM

3 transformers 600v to 7.2KV connected D-Y = 12.470v phase to phase; 7.2 phase to neutral. If I were to connect them Y-Y what voltage would I get Phase phase, and phase to ground? PRJM
