What is a Capacitor Bank?
A capacitor bank is a group of several capacitors connected in the series or parallel combinations. Capacitors are electrical and Inductive loads such as coils, motors, etc. have lagging power factor. Capacitive loads for example capacitors have leading power factor, and resistive loads for example heaters have unity power factor. ...
