Partial Discharge Coupling Capacitor 12kV rms / 1000pF Nominal Voltage 12kVrms Build in Quadrupole with voltage reference output Build in Overvoltage Protection Capacitive floating Signal output to avoid Eddy Current Loops General Description Hydro Generators Turbo Generators Windmills Industrial Motors 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 PDC12-1000 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. The Signal output is protected via 90V surge arrestor. The ’shield’ of the coaxial output is capacitive floating through a 1uF Capacitor to avoid eddy currents in the signal cables due to high magnetic fields.
