Transformer Oil Test Set Features & Advantages:

6.1.2 the capacity of the source shall be sufficient to maintain the test voltage until dielectric breakdown occurs. This test were carried out by providing a high voltage to the paper located between stem electrodes until a puncture isolation failure occured [6]. The test may be carried out five to six times and the average of these readings can be considered as breakdown voltage of insulating oil under test.
