Calculation of Capacitor (KVAR) required for P.F improvement

1)  Using formula

P = Power in KW

Cos Φ1 – Present P.F

Cos Φ2 – Target P.F

 kVAr required = P ( tanφ1 - tanφ2 )

2) Using Multiplier Table

Multiplier value  X  Present  KW

             Power Factor improvement

         Capacitor requirement for direct connection to Motor
