Power factor is important in the A.C. circuit because the apparent cuirrent flowing through the circuit is more when power fator is less than 1.
For purly Inductive circuit the power factor is zero. similarly for purly resistive circuits the power factor is 1.
so it is always desirable to approach towards unity power factor.
To achieve unity power factor AUTOMATIC POWER FACTOR CONTROL PANEL is used.
Automatic Power Factor Controller, consists of capacitor banks which are added to the circuit as and when required.
We manufacture automatic Power Factor Control Panels with contactor logic & thyristor controlled also, with & without reactors ( harmonic filters )
