Title: Some factors that influence the breakdown voltage of biodegradable transformer oil

Abstract: This work investigates the variability of the breakdown voltage of biodegradable transformer oil used in high-voltage devices under specific conditions of the experiment. The breakdown voltages of transformer oil were measured for different numbers of breakdowns in the measurement series, different electrode geometries and different levels of moisture. The test results showed that the breakdown voltage of ester oil in a homogeneous field depends on the geometry of the electrodes, both for dry and moist oil.

Key words: transformer oil, ester, breakdown voltage, moisture
