Description

Our R & D has developed partial discharge coupling capacitor. This special type of capacitor is used to couple PD signal and fed to the measuring instruments. PD signal is developed from defected or damaged insulation of transformer wires used mainly in sub-station, motor winding insulation, XPLE cable insulation etc. PD coupling capacitor is energized and coupled signals when the discharge occurs in any void between the copper conductor and insulation wall or internal to the insulation itself.
