Resource Category: Electrical Discharges

Partial Discharge could appear in any point of the insulation system as electrical stress, by exceeding the dielectric strength.

Electrical discharges (ED) in MV power circuits are (1) Partial Discharges (PD) and (2) Partial Arcing (PA). Partial Arcing is a term coined by Martec to explain multiple findings which exhibit some common characteristics of PD.

Unconventional PD measuring (IEC 62478) methods and systems can detect PD signals, identifying different physical characteristics and properties of the PD.
