DEFECT LOCALIZATION INSIDE SIMULATED MV SWITCHGEAR BASED ON CUMULATIVE ENERGY CURVE USING TRANSIENT EARTH VOLTAGE SENSORS

Defect Localization Inside Simulated MV Switchgear Based on Cumulative Energy Curve Using Transient Earth Voltage Sensors

The partial discharge (PD) leads to catastrophic failure of the medium voltage (MV) switchgear insulation.Determination of the PD source (defect) location in high voltage (HV) equipment is very important in the maintenance procedures and in isolating the root cause of PD generation.In this paper, the transient earth voltage (TEV) detection method w
