Good insulation function in transformers is a major concern in the reliability of electrical energy distribution systems. Transformers serve as key components requiring effective insulation systems. This study analysis the time period of partial discharge (PD) phenomena in automotive engine oil using needle-plate electrodes with two detection components: HFCT and loop antenna. Testing was conducted 10 times with parameters including BGN on/off, positive/negative PDIV, PDIV × 1.25, and PDIV × 2. Results show automotive engine oil PDIV (2.0 kV) is lower than transformer oil (2.35 kV). PD time period in automotive oil was 6-6.4 μs, while transformer oil was 6.8 μs. Positive PDIV frequency in automotive oil (166.7 Hz) was higher than negative PDIV (156.250 Hz), while transformer oil had equal frequencies (147.1 Hz). The study concludes that PD in automotive engine oil insulation is more severe compared to transformer oil, with transformer oil demonstrating superior insulation strength. Keywords: insulation, PD, frequency, needle-plate electrode.
