low power factor
low power factor
(OP)
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 temporary feeder cables which at several points where bundled together, instead of usual practice of segregation. Could there be any other reason for this?





RE: low power factor
At low load, motors have low power factors. Power factor goes up as the motor load increases.
The grouping of the feeder conductor may have a very slight impact on the inductance of the feeder, but tighter bundling would actual lower the inductance. But these are third or fourth order effects when compared with impact of the load power factor.
