Y5WZ lightning arrester is a kind of lightning arrester based on metal oxide nonlinear resistance characteristics, mainly used for overvoltage protection. The working principle is that under the normal working voltage, the arrester presents a high resistance state, which does not affect the normal operation of the power system; When the power system is subjected to overvoltage, the metal oxide resistor in the arrester will act quickly, showing a low resistance state, and introduce the overvoltage energy to the ground, thereby limiting the amplitude of the overvoltage and protecting the power equipment from damage .
