9230/25/1-PD Coupling Capacitor
The 9230/25/1-PD is a 25 kV coupling capacitor with an integrated measuring impedance and high voltage filter in a compact design for partial discharge measurements. 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 over-voltage by a mechanical spark gap.
