Photovoltaic (PV) plants are composed of many panels supported on large metal structures, located in open areas and normally highly exposed to the electrostatic perturbations caused by lightning.

Capacitor differential protection tips

This overcurrent relay detects an asymmetry in the capacitor bankcaused 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. Faulty elements in a capacitor unit are. Capacitors of today have very small losses and are therefore not subject to overload due to heating caused by overcurrent in the circuit. The capacitor can withstand 110% of rated voltage. In addition to the relay functions described above the capacitor banks needs to be protected against short circuits and earth faults. This is done with an.
