A unit of a capacitor bank is normally called a capacitor unit. These units are typically manufactured as single-phase units and connected in star or delta configurations to form a complete three-phase capacitor bank.
The main types of capacitor banks used in substations are shunt capacitors and series capacitors. Shunt capacitors are connected parallel to the load, improving voltage regulation, while series capacitors are connected in line with the transmission path to reduce losses and enhance stability.
