Abstract :
Dielectric breakdown values were measured in 50- 150 mm gaps in natural ester fluid and mineral oil. The tests included 50/60 Hz and 1.2×50 μs lightning impulse using negative and positive polarities. The voltage levels attained by natural ester fluid compare closely with mineral oil and would support the use of natural ester fluid in transformers through power insulation classes.
