ANALISIS TEGANGAN TEMBUS SILICON OIL AKIBAT PENUAAN TERMAL DAN PARTIKEL KERTAS KRAFT DALAM TRANSFORMATOR TENAGA

---

Silicone oil is one of the insulating liquids used in power transformers due to its high thermal stability and excellent dielectric properties. However, during operation, this oil may degrade because of thermal aging and contamination by solid particles such as Kraft paper. This study aims to analyze the effect of thermal aging and the presence of Kraft paper particles on the breakdown voltage and dielectric dissipation factor (tan δ) of silicone oil. Samples of pure silicone oil and silicone oil contaminated with Kraft paper particles were heated at 140°C for 50, 100, and 150 hours. The breakdown voltage test was carried out using a sphere–sphere electrode with a 2.5 mm gap, while the tan δ test was conducted using a semi-automatic Samgor QS30A bridge. For pure silicone oil, the tan δ value increased from 1.776×10⁻⁴ to 5.346×10⁻⁴, while the breakdown voltage decreased from 53.7 kV to 45.8 kV. For silicone oil containing Kraft paper particles, the tan δ increased up to 6.856×10⁻⁴ and the breakdown voltage decreased to 39.6 kV. These results indicate that thermal aging and Kraft paper particles accelerate the degradation of the dielectric properties of silicone oil. The tan δ and breakdown voltage tests can be used as early indicators to detect the decline in transformer insulation quality.
