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

In power generator sets, when they are coverted from 50hz to 60hz, the kva rating after conversion increases. For example, the manufacturer of a perkins 200kva @ 50Hz generator set has mentioned it to become 220kva after converstion to 60hz. What is the relation between the frequency & the KVA rating. Any formula please.
