Abstract
PURPOSE: To continually monitor the deterioration conditions of a non-linear resistor, by detecting a resistance portion of the leakage currents of an arrester at all times.
CONSTITUTION: An electrode 10 is mounted in a shape that is opposed to a high- tension portion conductor 9 of an arrester, and arrester terminal voltage is detected by using impedance connected between the electrode and an earth. Arrester leakage currents are detected by employing a current detecting resistor connected between the earth side of the arrester and the earth. The resistance component currents of leakage currents are detected from the arrester terminal voltage and the arrester leakage currents detected in this way. Thus, the deterioration conditions of a non- linear resistor can continually be monitored.
