Partial Discharge Couplers

Keeping in mind the ever-evolving requirements of our precious clients, we are offering an exclusive range of Partial Discharge Couplers to the clients from New Delhi. The 1000pF coupling capacitor is a sensor used for online and offline partial discharge measurements on rotating machines. The sensor will be usually installed at the busbar or on the high voltage terminals of the rotating machine. Permanent or temporary partial discharge detectors / analyzers can be connected via standard RG58 BNC cables to the coupler, usually by using a termination and safety box in between.

The PDC17.5-1000 has an M12 High Voltage Terminal to connect the coupler to the high voltage terminal. The cable is usually connected via cable lugs to the high voltage busbars of the rotating machine to pickup partial discharge signals without any loss. A specially designed measurement impedance located in the base of the sensor allows to pick up partial discharge signals as well as the line frequency (1:2000). This allows to transfer partial discharge signals and line frequency signal over the same cable to the partial discharge detector.
