Yeah mate; for a number of years after completing my apprenticeship moving coil meters were all we could get and they had their place; the ohms/volt on many wasn't especially high. All our test gear now is digital - a sign of the times I guess.
Anyway, I bit the bullet on this job because all...
Thanks once again, waross; when I did the lamp test earlier (generator still in double delta) I only used a 10w LED one, figuring that any "stray" currents wouldn't be of much magnitude but maybe they are. The 10w lamp did light up and the terminal to frame voltage didn't plunge when the lamp...
Thanks for all that Waross and yeah, I was a bit liberal with terms like earthed, etc - that's why they were in parenthesis - and I had pretty much already done the tests you suggest in the following way. With the AVR still connected I did a continuity test from the generator frame to all 6...
thread237-405800. I'm in a similar situation with a small Stamford unit bought 2nd hand by a client with no manuals or a maker's name plate showing model number, etc; supposedly about 12KVA, 240VAC, 1Ph, 50Hz and because I could see the single red, black and green cables coming from the terminal...
