Leading versus lagging power factor
WebAt this minimum point, the motor is operating at a unity power factor. The motor operates at a lagging power factor until it reaches up to this point of operation. If now, the field current is increased further, the armature current increases and the motor starts operating as a leading power factor. Web4 okt. 2024 · In case of leading power factor, the current leads the voltage whereas; in lagging power factor, the current lags the supplied voltage. The load conditions depend on the propensity of the circuit, which causes the current to either lead or lag. Which is better leading or lagging power factor? difference betweenelectronics 22 Answers 0 Share
