Why capacitor bank is used?

3 Answers

Answer :

Capacitor banks are mainly placed in the substation used to improve and to lead the power factor

Answer :

Power factor improvement so to balance active and reactive power to safe guard the generation system.

Answer :

In industrial or factory used E.B Power supply must be maintained above 0.90 power factor is compulsory for avoid EB Penalty. So APFC ( automatic Power factor control ) panel is used to maintained balance the load and PF maintained.
