Identification of Electric Discharge Location and Magnitude Using Double Quad Electric Field Sensor

초록

Defects in gas or liquid or solid insulator of high voltage equipment make the electric discharge or the similar phenomena which may degrade the electrical insulation status of them. The information about such defects is very important to prevent it being worse and eventually becoming blackout by the insulation failure of high voltage equipment in substation or another application. This paper has investigated the methods identifying 3-dimensional location of electric discharge which will be generated on defects. Double quad electric field sensor is suggested to be such a proper one that can be some solution of calculating the magnitudes of electric charge as a electric discharge. Those were evaluated from the results of simulation by commercial multiphysics software for the electric discharge between double quad electric field sensor which are deployed in the two sided planes with Cartesian coordinate system. The location and magnitude of Unknown electric charge could be inferred from the results of simulation by commercial software.
