Ok so here is my problem. I am trying to troubleshoot a generator breaker feeding a transfer switch and the gen breaker keeps tripping. Breaker is 1000a @ 480v
It will run for at least an hour carrying building load with no problem. After an hour its touch and go. Tripping anywhere from 1hour...
I am receiving noise even when circuit breaker and ground are detached from residence. Any help reading my oscilloscope readings would be helpful! If you can help...let me know and I will send you the PDFs of my wavelengths. Thanks!
VFDs must create lots of harmonics on the power line since their output is non-sinusoidal or distorted sinusoidal.
That being said, are supply wires for VFD pumps and motors typically larger than those for standard AC pumps and motors of the same horse power?
