Capacitor bank protection 1. Unbalance relay. This overcurrent relay detects an asymmetry in the capacitor bank caused by blown internal fuses, short-circuits across bushings, or between capacitor units and the racks in which they are mounted.. Each capacitor unit consist of a number of elements protected by internal fuses.
Capacitor banks are made up of individual capacitor units that are in turn connected in a variety of series/parallel combinations. The function of fuses for protection of the shunt capacitor elements and their location, external or internal to the capacitor unit is part of the design of shunt capacitor banks.
