WebA power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA) and is required to calculate the power factor. The power factor formula can be written as, PF = (True power) / (Apparent power) Or PF = W / VA Here, watts is used to measure the power used by the system and VA measures the power supplied. WebHere the current reaches zero before the voltage. Hence we can say that the current leads voltage by 90 deg. (angle as per diagram). This is called leading current. The Leading current can be called as leading Power factor.
