Mobile capacitor bank
The mobile capacitor banks is a packaged factory assembled and tested reactive compensation system with modular fixed or switched capacitor steps, which automatically compensate an individual load or the network to maintain a preset level of power factor. The capacitor bank is mounted on a trailer and can be moved from one substation to another.
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.
