PENGARUH KETEBALAN LAPISAN SiO2 TERHADAP NILAI PELUAHAN AWAL SEBAGIAN DAN TEG…
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…

ANALISIS TEGANGAN TEMBUS SILICON OIL AKIBAT PENUAAN TERMAL DAN PARTIKEL KERTA…
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 …
