More Information


9230/20/1-PD - Coupling capacitor 20 kV for Partial Discharge measurement The coupling capacitor (PSF - Power Separation Filter) type 9230/20/1-PD includes in a compact design the high voltage capacitor, the high voltage filter and the measuring impedance. It is optimized for measuring partial discharges together with the PD detector DDX 9121b.An incorporated half-T filter on the high voltage electrode attenuates the interferences coming from the power supply and increases the sensitivity of the PD measuring circuit. The filter is protected from overvoltage by a mechanical spark-gap.

  • All in one solution including the coupling capacitor, the HV filter, and the measuring impedance.
  • PD free (&
  • lt 1 pC)
  • perfect solution for onsite measurements of rotating machines (together with MIDAS and DDX 9121b).
  • Portable &
  • amp
  • Voltage/synchronization output.
