The effect of cellulose particles on streamer and breakdown phenomena in a synthetic ester and a mineral oil was investigated using a non-uniform point-plane electric field and a uniform plane-plane electric field under standard lightning impulse voltages. Oil samples were prepared to be low and high contamination levels according to CIGRE brochure 157. A multi-frame high-speed camera was used to...
This paper presents experimental studies on the effect of cellulose particles on breakdown voltages and breakdown mechanisms of a synthetic ester and a natural ester under standard lightning impulse voltages. A mineral oil was also tested and used as the benchmark. In total, liquids with four particle contamination levels, i.e. low, normal, marginal and high; two moisture levels, i.e. dry and wet...
