DAMAGE DETECTOR, DAMAGE DETECTION SYSTEM, AND DAMAGE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To detect a damage of a part of elements constituting a gas insulation arrester.;SOLUTION: A damage detection unit receives sensor data showing a detected physical quantity from a sensor for detecting the physical quantity corresponding to the temperature of the gas in a tank of a gas insulation arrester. The damage detection unit detects a damage of a part of elements on the basis of the received sensor data. In more detail, the damage detection unit determines that a part of the elements is damaged when the physical quantity is increased by a thunderstroke and when it is detected that the behavior of the increase depends on the tank, gas, and a thermal time constant of the structure in the tank.;COPYRIGHT: (C)2015,JPO&INPIT
