Types of High Voltage Surge Arresters 36kV Surge Arrester 66kV Surge Arrester 110kV Surge Arrester 220kV Surge Arrester 330kV Surge Arrester 500kV Surge Arrester 1000kV Surge Arrester Working Principle of High Voltage Surge Arresters The working principle of high voltage surge arresters is based on the principle of providing a low impedance path for transient currents caused by high voltage surges. High voltage surge arresters operate by using non-linear resistance elements made of metal oxide varistors or silicon carbide. These materials provide a high resistance under normal operating conditions but switch to a low resistance state in the presence of high voltage surges. When a surge occurs, the surge arrester conducts the excess energy to the ground, reducing the peak voltage level that the equipment is exposed to, ensuring the equipment is protected from damage. The high voltage surge arresters can also operate with high energy, fast response time, and frequent surge stress, making it a reliable and effective protection solution for high voltage power systems. Proper installation and testing of high voltage surge arresters are essential for effective performance.
