In an experiment for determining the breakdown strength of transformer oil with standard electrodes, the following observations were obtained with two different types of oils (Oil A and Oil B). Oil A breakdown voltage is 165KV at 8mm gap spacing and for the same gap space Oil B break down Voltage is 0.140MV. For 16mm gap spacing, the breakdown voltage is 212 KV and for the same gap spacing, Oil B breakdown voltage is 200KV.
