High voltage capacitors for partial discharge or AC measurement

More Information


The HAEFELY HIPOTRONICS  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.

  • BNC outputs for PD and voltage readings
  • High stability in capacitance values
  • Large base frame with heavy duty swivel casters
  • Large measurement bandwidth
  • PD free ( &
  • 1pC)

  • Save room in the HV laboratory: With our compact all in one solution, coupling capacitor, measuring impedance and (optional) high voltage filter in one single unit, the amount of necessary devices for performing a test re reduced
  • Reliable results: Large measurement frequency bandwidth, high stability in capacitance values with frequency and temperature guarantee a consistent and reliable measurement
  • Increase your sensitivity: With the optional HV filter interferences from the HV power supply are sufficiently suppressed and sensitivity of the test circuit is increased
