HIGH VOLTAGE (60kV - 216kV)

HIGH VOLTAGE (60kV - 216kV)

Polymer Surge arresters are used to protect electrical equipment, like transformers, circuit-breakers, and bushings, against the effects of over voltages caused by incoming surges. Such over voltages can be caused by a direct or nearby lightning strike, an electromagnetic pulse, electrostatic discharge, or switching operations in the power supply system as well as in devices. Some over voltages are very high in energy. The current from the surge is diverted through the arrester, in most cases to earth. Effective overvoltage protection requires different surge arrester types to be used according to the particular application.
