9230 Coupling Capacitor

The Haefely  9230 high voltage  capacitor  consists of a modular HV capacitor with appropriate coupling impedance fitted in for partial discharge measurements.The high voltage  capacitor is a part of the partial discharge measuring circuit. A closed loop for the high frequency PD signals is established between the test object and the coupling capacitor. The PD pulses are then captured by the measuring impedance and brought to the PD detector.
