Catalogue excerpts

Partial discharge level of power cable is closely related to its insulation properties and the change of partial discharge means there are defects that may endanger safe operation of the cable. So the accurate measurement of power cable partial discharge is the most effective way to check the performance of the cable insulation. As partial discharge measurement can find defects in a concentrative manner and bring very small damage to cable; experts, scholars and the international electric power authoritative organizations such as IEC, IEEE, CIGRE agree that: partial discharge test is the best...
