Definition of breakdown voltage of insulating oil
The breakdown voltage of insulating oil refers to the voltage required under specific conditions when the electric field strength in a unit thickness of insulating oil medium reaches the breakdown strength of the insulating medium, usually expressed in kilovolts (kV). The breakdown voltage of insulating oil is one of the important indicators for insulating oil as an insulating medium in power equipment, and it is also an important indicator for evaluating the quality of insulating oil.
Factors affecting the breakdown voltage of insulating oil
1. Types of insulating oil: Different types of insulating oil have differences in breakdown voltage;
2. Processing technology of insulating oil: The processing technology of insulating oil can also affect its breakdown voltage;
3. Oxidation degree of insulating oil: The higher the oxidation degree of insulating oil, the lower its breakdown voltage;
4. Impurities contained in insulating oil: The higher the impurity content, the lower the breakdown voltage.
