WebAug 3, 2024 · Also reactive power is supplied by consumer to grid in case of excessive capacitive load. It is measured in kVAr (Lag / Lead) and is totalized by the energy meter as kVArh (Lag / Lead). At present, Consumers are billed on Active Energy Consumption measured in kWh along with the fixed charges and other charges. What causes lagging … WebApr 1, 2024 · Reactive power is a concept that comes out in AC circuits where the voltage or current sources have a sine wave shape with a certain fixed frequency f. Picture this circuit: a sine wave voltage source V that charges and discharges a capacitor C. They are in parallel. Vc (t) = V * sin (2 * pi * f * t) V and f are fixed.
http://www.differencebetween.net/technology/difference-between-leading-and-lagging-power-factor/ WebJan 12, 2006 · Remember, that leading and lagging is always measured using the voltage (or real power, which is in phase of the voltage). Therefore, negative Q is lagging the voltage and positive Q is leading the voltage. Using the convention, you should rewrite your implication to be: Lagging PF = Leading Q = Positive Q Also, Leading PF = Lagging Q = Negative Q
