The main reason for testing the dielectric strength of insulating oil is that the dielectric strength of insulating oil is an important index reflecting the quality of insulating oil, and this index can directly reflect the withstand voltage capability of insulating oil. The dielectric strength of insulating oil is a general term for the breakdown voltage, breakdown strength, and withstand voltage capability of insulating oil. The higher the dielectric strength test result of insulating oil, the better its insulation performance. Therefore, use the insulating oil dielectric strength tester to test the dielectric strength of the insulating oil on a regular basis or when necessary. This can effectively detect the insulation performance of the insulating oil.

In electrical equipment, insulating oil is widely used as an insulating liquid in electrical equipment, such as power transformers, etc., and the insulating liquid filled inside is insulating oil liquid. Insulating oil can isolate the air and increase the insulation strength of the transformer. For the insulation of transformer windings, it can also play the role of moisture-proof, accelerated cooling, and accelerated arc extinguishing. With the long-term operation of electrical equipment, the insulation performance of insulating oil will gradually decrease due to the influence of high temperature, humidity, oxidation, electric field, impurities and other factors. Therefore, in order to maintain the normal and safe operation of electrical equipment, various tests are carried out on the insulating oil regularly are very necessary.
