It is not recommended to keep power factor leading:

1) We try to keep power factor unit to reduce transmission
losses, this main purpose will not achieved by keeping
leading power factor. If power factor is lower than unit
(it can be leading or lagging) transmission loss will
increase.
2) During leading power factor if we make any breaker
operation (close/open)it will generate high voltage across
breaker, which is harmful to breaker. For capacitive load
operation we need a special breaker.
3) It is not correct that keeping leading power factor
shows more KW and less KVA.

Yes there is effect on electrical system.The power will be
lost and could not maintain the voltage in the capacitor
bank system. so we can keeping power factor in leading
shows more KW and less KVA.It is correct.

75kw drive operated motor current fluctuation from(85-130)ampere.current setting in drive is 130amp.sometimes motor trip when current limit cross 130amps.I change the drive. still current fluctuate between 80-130amps but in this time motor not trip,current setting in drive is 130amps.where is the problem?
