PENGARUH KONSENTRASI PENGISI MAGNESIUM OXIDE DAN ZINC OXIDE TERHADAP NILAI TEGANGAN AWAL PELUAHAN PARSIAL DAN TEGANGAN TEMBUS PADA MATERIAL ISOLASI EPOXY RESIN
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 performance compared to the control sample. The PDIV of the MgO samples increased from the control's 1,56 kV to 1,91 kV; 1,96 kV; 2,12 kV; 2,05 and 1,97 kV. For the ZnO samples, PDIV increased to 1,73 kV; 1,81 kV; 1,93 kV; 2,04 kV and a peak of 2,18 kV at 4 wt%.For breakdown voltage, the of the control sample 17,53 kV increased to 19,72 kV; 19,32 kV; 23,31 kV; 20,94 and 19,68 kV with 1–4 wt% MgO. With ZnO, the BDV increased to 19,05 kV; 19,50 kV; 20,78 kV; 21,15 and 21,79 kV. These results indicate that the optimum filler composition for MgO is 3 wt%, while ZnO provides a more stable increase up to 4 wt%.
