Thanks for the information, and I believe electricpete had given me an idea since our only load without the compressor motor is the UPS, which is actually seen as a transformer running at very low load at the moment, since only a few circuits had been energized.
We have a 1000 kw, 400v, 50 hz generator working for commissioning. Since beginning, we experience low power factor when load is less, typically .45, but when the compressor motor, rated 250 kw, started running, power factor increases to .81. I suggested the cause can be attributed to the...
