Method of estimating location of partial discharge using signal attenuation rate in GIS tank

摘要

Provided is a method of estimating a location of partial discharge using a signal attenuation rate in a gas insulated switchgear (GIS) tank. The method includes a process (S 100) of constructing a coordinate system database of each tank of the GIS, a process (S200) of constructing an electromagnetic wave signal attenuation rate database of each structure of a GIS, a process (S300) of performing a location estimating algorithm, and a process (S400) of determining the tank at which the partial discharge occurs based on a result of performing the location estimating algorithm.
