Answer / srinivasa rao talasila

There is a formula to calculate capacity of capacitor
required for a certain inductive load in KW
KVAR=KW*(Tan of running PF angle-Tan of desired PF angle)
Per suppose my plant is running 0.84 i need to take it to
0.98 at a load of 800KW

KVAR=800*(Tan 32.86-Tan 11.48)
KVAR=800*(0.6459-0.2030)
KVAR=800*0.4429
=354.32 say 355KVAR
