What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

Partial discharge (PD) is defined as a localized, high-frequency arcing that only partially bridges the insulation between multiple conductors or between conductors and the ground wall of an ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...
