Reactive power is the power required by the machine for its working eg: a 10 kW motor normally takes 14 kW from line. In this the active power is 10 kW only but the 4 kW is required by the machine to deliver the 10 kW 

Answer / sreenvas

but i know

active power means vicos pi
reactive power means visin pi

reactive power is also out phase of voltage with currents
that means current is maximum, voltage is postive or negative ...

what is the meaning of powerfactor

Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
