The quality of transformer insulating oil is directly related to the safety of transformers and grid systems, because the insulating oil of transformers has the function of insulation, arc extinguishing and cooling. In order to ensure the good performance of the transformer during operation, it is necessary to carry out various tests on the transformer oil regularly. Since the oil breakdown voltage test conditions are strict, the withstand voltage test of the insulating oil is carried out in a special breakdown voltage tester. The JY6611 transformer oil breakdown voltage tester is developed according to the IEC-156:1995 standard and is an ideal measuring instrument for oil breakdown voltage testing.
Here's how JY6611 oil breakdown voltage tester (oil BDV tester）oil dielectric tester tests the transformer oil breakdown voltage.
