The 9231/30/9-PD is a 30 kV coupling capacitor with an integrated high voltage filter and low voltage termination to connect an external measuring impedance in a compact design for partial discharge measurements. It is optimized for measuring partial discharges together with the PD detector DDX 9160 or DDX 9161. 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 over-voltage by a mechanical spark gap.
