In normal service, tripping on faults is done through the diode bridge rectifier"s dc supply. In abnormal conditions of failure of HT PT supply, the tripping energy is derived from energy stored in the charged capacitor banks. Normally the capacitors are rated to store energy for two trip and one close operation. The scheme is shown in Figure 5.

An automatic capacitor bank is a device that, after detecting the presence of inductive reactive energy above the desired value in an electrical installation, acts by automatically connecting capacitor groups (steps) necessary to adapt to the demand and keeps the PF roughly constant (IEC 61921, 2017). The optimization model of capacitor
