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

An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The rotor reactance at stand still is A 2 ohm B 1.25 ohm C 3.15 ohm D 2.25 ohm
