How to calculate the size of capacitor bank to improve the power factor of a system If you are searching a way to know how to correlate power kW and the required kVAR rating of capacitor. Thumb Rule Formula – required kVAR =  Power X Multiplying Factor (Table given below) Or in detail you can solve by given formula Required kVAR =  power (tan A – tan B) For example –  Power = 100 kW, P.F is 0.75 and required P.F is 0.9 Solution – Multiplying factor from table from 0.75 PF to 0.9 PF= 0.398 From above formula the […]
