The combination of surge arresters and surge capacitors serve to limit the turn-to-turn insulation stress on the device being protected. Why Hitachi Energy? Hitachi Energy's motor surge protection bank (MSP) is designed to limit the turn-to-turn insulation stress imposed on the device being protected.
GE TRANQUELL Arresters work effectively with GE Surge capacitors to provide additional security for AC rotating machines. Arresters limit the amplitude of applied impulse waves or reflections within the machine windings, reducing the effects of lightning stresses.
Installation of arresters also minimizes probability of restrike, especially of multiple restrikes. This edited past contribution to INMR by Tim Rastall and Kerim Ozer of Enspec Power in the United Kingdom discussed application of surge arresters for mitigation of overvoltages on MV & HV capacitors based on single restrike.
Surge Arrester Energy Requirements • Compared to a standard capacitor bank, surge arresters in detuned designs absorb more energy; • Increasing detuning frequency brings about less absorbed SA energy in the detuned design. However, it is still higher than the SA energy in a standard capacitor bank;
