The characteristics of partial discharge (PD) on porcelain-based ceramic disc insulators under various test voltage levels, namely 5 kV, 10 kV, 15 kV, and 20 kV, were investigated. The collected data included the highest and lowest PD amplitudes in decibels (dB) and PD phase angles in degrees, which were visualized using line graphs. The purpose of this study was to understand the phase distribution patterns of PD in relation to amplitude and applied voltage, which can provide indications of the insulation condition of the material. The analysis shows the presence of repetitive PD phase patterns (90°, 180°, 270°, and 360°) under most voltage and amplitude conditions. Phase fluctuations accompanying changes in amplitude indicate the dynamic behavior of partial discharge activity within one voltage waveform cycle. These patterns are consistent at low and medium voltage levels; however, at the highest test voltage (20 kV), porcelain-based ceramic discs tested at 5 kV, 10 kV, 15 kV, and 20 kV still exhibit consistent repeating PD phase patterns at 90°, 180°, 270°, and 360° across the entire tested voltage range.Although PD amplitudes vary between maximum and minimum values at each voltage level, the phase patterns tend to preserve their basic shape.
