9230/20/1-PD – Coupling Capacitor 20 kV for Partial Discharge Measurement
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.
