Thanks, everybody, for your input. I spaced on the fact that the output is generated off the DC bus, and therefore unnaffected by input voltage imbalances. My focus has been on monitoring the long term heat effects of the imbalance shortening the life of my line driven motors, and I carried that...
Can the current draw on three phase motors run off VFD's be checked the same as line powered? I have a number of small motors (2 to 15 hp) run off VFD's I'd like to monitor as part of a preventative maintenance program. At times I have to contend with a slight supply voltage imbalance and would...
