PD level of power cable is closely related to its insulation properties and the change of PD means there are defects that may endanger safe operation of the cables. So the accurate measurement of power cable PD is the most effective way to check the performance of the cable insulation. As PD measurement can find defects in a concentrative manner and bring very small damage to cables. Experts and scholarts and authoritative organizations such as IEC, IEEE, CIGRE agree that PD test is the best way to evaluate XLPE insulated power cable insulation conditions and important method to discover the hidden dangers of cable fault, forecast cable operating life and ensure cables safe and reliable operation. Therefore, PD test and fault location during AC voltage test becomes an important means of the power cable test.
We supply such test systems for AC voltage withstand test, PD measurement and fault location.
All products comply with IEC standards.
