Abstract

Partial Discharge (PD) is the dissipation of energy caused by the buildup of localized electric field intensity. In high voltage (Tension) device such as Cables, transformers, electrical machines etc., this buildup of charge and its release can be symptomatic of problems associated with aging, such as voids, floating component and insulation breakdown. In the Power System Electrical Power cables must be designed as rugged and flexible. The use of power electronic devices cause voltage spikes and introduce harmonics that electrically degrade the insulation of the electrical cables and all kind of equipment using in the power system. Power electronic driver circuits required high frequency and high operating temperatures, which affect the aging and breakdown properties of the cable insulation. In many high voltage systems, breakdown voltage is an indication of insulation condition. Partial discharge presents issues in electromagnetic compatibility as a noise source.
