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 &
- Voltage/synchronization output.
