WebIn Michigan I've gotten breakdown as low as 12 kV/cm in the humid summers, even in an air conditioned lab. The dryer the air, the higher the breakdown voltage. $\endgroup$ – … WebA stage comes when the final breakdown oil takes place and the circuit breaker is tripped which disconnects the testing set from the mains supply. This value is noted down which must be 30 KV (RMS) for 4mm gap and 20 KV (RMS) for 2.5 mm gap. The test is performed with two or three consecutive samples of oil turn by turn.
WebThe logic of breakdown remains the same. From my experience, untreated, raw transformer oil has to withstand 40 kV per 2.5 mm for 1 minute (rate of rise of the voltage : 2 kV/s). … WebDec 8, 2016 · or for centimeters: voltage (kV) = 30 x spark length (in cm) That’s just another way of saying that there’s 30kV/cm.
