1) For a starting P.F. other than 0.6, the starting kVA must be multiplied by K = Sine φ /0.8
Calculation example for a different P.F. : Starter motor kVA calculated at 0.4 P.F. = 750 kVA
Sin φ 0.4 = 0.9165
K = 1.145
kVA corrected = 858.7 kVA
Voltage dip corresponding to L11 = 12 %.
2) For voltages other than 400V (Y) , 230V ( ) at 50 Hz, then kVA must be multiplied by (400/U)2 or (230/U)2.

1) For a starting P.F. other than 0.6, the starting kVA must be multiplied by K = Sine φ /0.8
Calculation example for a different P.F. : Starter motor kVA calculated at 0.4 P.F. = 750 kVA
Sin φ 0.4 = 0.9165
K = 1.145
kVA corrected = 858.7 kVA
Voltage dip corresponding to L11 = 10 %.
2 ) For voltages other than 480V (Y), 277V ( ), 240V (YY) at 60 Hz ,
then kVA must be multiplied by (480/U)2 or (277/U)2 or (240/U)2.
