PENGARUH KETEBALAN LAPISAN SiO2 TERHADAP NILAI PELUAHAN AWAL SEBAGIAN DAN TEGANGAN TEMBUS PADA BAHAN KOMPOSIT EPOXY RESIN

This study aims to determine the effect of variations in SiO₂ layer thickness on the Partial Discharge Inception Voltage (PDIV) and Breakdown Voltage (BDV) values in epoxy resin composites. The SiO₂ layer was prepared using a TEOS-based sol-gel method and applied by spray coating technique on the sample surface. The thickness variations tested were 20 µm, 30 µm, 40 µm, 50 µm, and 60 µm, as well as an uncoated sample as a control. The test was carried out using a needle-plate electrode system with an AC voltage that was increased until the first PD appeared and until breakdown occurred. The test results showed that SiO₂ coating significantly increased the PDIV and BDV values. The PDIV value increased from 1,519 kV (control) to 2,040 kV at a 60 µm layer, while the BDV increased from 16.8 kV to 20.4 kV. This improvement is due to surface improvement, closed micropores, and more even electric field distribution. However, certain thicknesses such as 50 µm show a slight decrease in BDV due to coating inhomogeneity. Overall, coating thicknesses of 40–60 µm have been shown to provide the best dielectric performance. Sol-gel and spray coating methods have been shown to be effective in improving the insulation resistance of epoxy resins for highvoltage applications.
