Power Factor correction


The AC electrical networks consume both active and reative power as we called ( Kw ) and ( Kvar ).

+ The real-active power ( P-Kw ) transmitted to loads such as motors, lamps, heaters...they are transformed into mechanical power, people called heat or light.

+ Reactive power (Q-Kvar ), used supply only mag-netic part of the machine where they have motors and transformers.

+ Apparent power ( S-KVA ) is combined vector of both active and reactive power.

+ Cos pi representation of power factor ( P/S ).
