9230/25/1-PD

The coupling capacitor type 9230/25/1-PD includes a high voltage capacitor, a high voltage
filter and a measuring impedance in a compact design.
It is optimized for measuring partial discharges together with the PD detector DDX 9121b.
A half-T filter incorporated with the high voltage electrode not only attenuates any
interference from the power supply, but also increases the sensitivity of the PD measuring
circuit. The filter is protected from overvoltages by a mechanical spark-gap.
