What is the transformer BDV tester?
BDV test means the Breakdown Voltage Test. This test is performed for verifying the dielectric strength of the oil of the transformer. Dielectric Strength is the maximum capacity to resist the voltage of insulating oil.
Analysis of the variation of breakdown voltage value in the test When the breakdown voltage of the transformer oil is tested, generally a cup of oil is tested 5 times, and the average value is taken.
How the oil BDV tester works?
The normal operation should be: after the test oil is full, let it stand for 10 minutes and then carry out the ascension test. After each breakdown, use the prepared clean glass rod to make a few times between the electrodes or gently vibrate the oil cup to achieve damage. The newly formed bridge between the electrodes can be left for 5 minutes for the next test.
Pay Attention when using the oil breakdown voltage tester:
The first time the breakdown voltage is extremely low: the first test may have some external factors caused by the oil injection into the oil cup or the surface of the oil cup electrode before the oil injection, so that the first value It is low, so it is necessary to carry out the sixth test and take the average of 2 to 6 times.
This transformer oil bdv tester meets multiple standards, select the appropriate and required standard for testing.
