Partial discharge (PD) is a electrical discharge that only partially overbridges the insulation between conductors. Generally PD appear as pulses of duration of much less than 1µs.


The significance of PD in the lifetime of insulations has long been recognised. Every discharge event causes a deterioration of the material by the energy impact of high energy electrons and causing chemical transformations of many kinds.
