Power Factor Calculator for Single Phase

Power in KW (input1) :

Voltage in Volts (input2) :

Current in Amps (input3) :

Single Phase Power Factor (output) :

*Note: Enter values in INPUT boxes and Press CALCULATE button to check OUTPUTS.

EXAMPLE#1 Power factor calculator for single phase:
INPUTS: Power(KW) = 10KW , Voltage = 120Volts, Current = 80Amp
OUTPUT: Single Phase Power Factor = 1.041

Power Factor Formula for single phase

Following is the power factor formula for single phase used in the calculator.

Power Factor Calculator for Three Phase

Power in KW (input1) :

Line Voltage in Volts (input2) :

Current in Amps (input3) :

Three Phase Power Factor (output) :

EXAMPLE#2 Power factor calculator for three phase:
INPUTS: Power(KW) = 10, V(L-L) = 120Volts, I = 80Amp
OUTPUT: Three Phase Power Factor = 0.602

Power Factor Formula for three phase
