What Is a Partial Discharge?
Discharge occurs only in a local area of an insulator, and does not penetrate between the conductors to which the voltage is applied. It can occur near the conductor or elsewhere. This phenomenon is called partial discharge.

- Partial discharge phenomenon mainly refers to
- In a solid dielectric with a gas or liquid, when the local field strength of the gas or liquid with breakdown field strength reaches its breakdown field strength, this part of the gas or liquid begins to discharge. Partial discharge is generally caused by the local electric field in the insulator or the surface of the insulator. Usually this discharge appears as a pulse with a duration of less than 1 s.
- Partial discharge of insulation will affect insulation life. With each discharge, the impact of high-energy electrons or accelerated electrons, especially long-term partial discharge, can cause multiple forms of
- 1. Partial discharge is a sign of local overheating and aging of electrical and mechanical components;
- 2. The partial discharge trend is an increase index of partial discharge over time. This is a tortuous process. It may decline at a certain stage, but rise at a certain stage. [1]
- Most of the faults of power transformers are caused by insulation failure, and the existing maintenance and insulation
