Sorry, I should have been more detailed. I need 50Hz power, not signal. Currently the client has a 56kVA rotary unit. They are looking for something in the 1-5kVA range. I do not however, know what it is they are testing. The voltage in the building will be 120/208V, 3phase, 4wire. I hope...
I am looking for a site (or manufacturer) with information on frequency generators. I am looking to simulate European (50Hz) waveforms for testing equipment. Anyone with any info on this topic would be helpful.
Well, as it seems, the problem is out of the building. Rather than starting to shut everything down and start searching for the ground fault, I had hydro in to verify the integrity of their service. They have confirmed that the problem is upstream of this building at an auto shop, operating a...
The location is in Toronto Canada. It is definitely a 600V Delta system. As far as lighting goes, it is all at 120V. As far as symptoms go, nothing has failed catastrophically yet. We will be checking C phase thoroughly for a ground fault, and I will let you know of the results.
I have a 3 phase 3 wire 600V service to a commercial building. The tenant experiences flickering or dimming of the lights, and her UPS's are constantly switching between battery and normal. This is consistent with a sag. Measuring on the line side of the main switch, we get:
A-B, A-C, B-C all...
