PD -
Shanghai Jiuzhi Electric Co., Ltd.
Partial discharges (PD), as defined by IEC60270, are localized dielectric discharges in a partial area of a solid or liquid electrical dielectric insulation system under high-voltage field stress. It can be caused by discontinuities or imperfections in the insulation system. PD testing thus gives an indication of deterioration of the insulation and is an indicator of incipient faults. In general PD will occur in systems operating at voltages of 3000 V and above; it should be noted though that in some cases PD can also occur at lower voltages.

Soken Electric Co. Ltd
Insulation materials in electrical equipment are used between a pair of electrodes; therefore it can be expressed as capacitors. Applying AC voltage to a capacitor with insulation materials causes an energy loss due to the leak current, the dielectric polarization, and the partial discharge. Because of this, the phase of the capacitor current is more delayed than that of a zero-loss current (reactive current) flowing in an ideal insulation material. The delay angle is called "Dielectric Loss Angle", and the tangent is "Dielectric Loss Tangent" (tanδ). Please refer to the technical guide explained in detail.
