Calculating motor power factor
Web% EFF is motor efficiency per motor nameplate. Power factor is the ratio of true power (kW) to apparent power (kVA). In the absence of power factor measurement tools, a … WebWhat Is Power Factor? The total power in units of kVA is given by: kVA = Volts * Amps * (Nph)1/2 * 10-3 where Volts and Amps are the measured rms voltage and current and N ph is the number of phases (1 or 3). The relation between total power, reactive power and real power is shown in the "power triangle". For AC service, total power is the
