This research investigates the enhancement of PDIV and Breakdown Voltage in Epoxy Resin insulation material filled with MgO and ZnO at concentrations of 1 wt%, 2 wt%, 3 wt , 3,5wt% and 4 wt%. Testing was performed using a needle-plane electrode with a 1 mm gap, and AC voltage was ramped up at 100 V/s for PDIV and 1 kV/s for . Test results showed that adding MgO and ZnO improved insulation perfo…
