HAI IAM VISSU,
IAM WORKING AS AN ELECTRICAL ENGINEER IN SPINNING MILL.
RECENTLY APSPDCL POWER BILLING ON KVAH INSTEAD OF KWH.
SO WE HAVE TO MAINTAIN PF 0.99 TO UNITY OR LEADING PF.
IF WE MAINTAIN LEADING POWER FACTOR , ANY DISADVANTAGES ARE THERE?
PLS LET ME KNOW.
Yes! There are definite problems. Your EB or DISCOM calculates the monthly average power factor by the formula PF = kWh/kVAh. Please note that you do not gain any big advantage even with leading power factor. Because even with leading power factor the kVAh is going to be more and kWh less. SO, you will still have poor power factor and will be penalised. There could be other probelms such as voltage boost, etc. with leading PF
