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.
Certainly, you will some advantages when the Power Factor will be high, but be carful, because if you have a capacitive PF, then it's possible that the level of voltage will be higher that will be danger for some sensitive equipments,so, for that reason the ideal value for PF is : 0.93-0.96 but not more, because if you try to achieve 0.99 then certainly during switching-off for 1 big step ( 50 or 60kVAR ) you will have a capacitive power factor.
