The main component of the metal oxide arrester's nonlinear resistance valve is zinc oxide, which has excellent nonlinear characteristics. Under normal operating voltage, the resistance value is very high, which is actually equivalent to an insulator. Under over-voltage, the resistance of the resistor is very small, and the residual voltage is very low. However, under normal operating voltage, the valve plate will deteriorate due to long-term power frequency voltage, which will cause changes in resistance characteristics and increase the leakage current flowing through the valve plate.
