Substation Components and Their Workings
Capacitor Bank. A capacitor bank is a group of capacitors connected in series or parallel combinations. Capacitor banks store reactive energy, which can compensate for reactive energy and improve the power factor. This leads to a more stable grid with higher transmission capacity and fewer transmission losses.
