Wuhan UHV specializes in the production of partial discharge testers, which can help many power workers to carry out all kinds of power tests more conveniently.
Partial discharge, mainly refers to high-voltage electrical equipment.
The insulator of electrical equipment is discharged locally under the action of a sufficiently strong electric field. This discharge is limited only by the fact that the insulation between the conductors is short and no conductive path is formed. Each partial discharge will have a certain effect on the insulating medium. Slight partial discharge has less effect on the insulation of power equipment, and the dielectric strength decreases more slowly. Strong partial discharge can cause the dielectric strength to decrease rapidly. This is an important factor that causes insulation damage to high-voltage power equipment. Therefore, when designing the insulation of high-voltage power equipment, the role of long-term operating voltage should be considered, and its insulation structure does not allow strong partial discharge to occur.
