9231/30/9-PD
The coupling capacitor type 9231/30/9-PD includes a high voltage capacitor, a high voltage filter and a low-voltage (LV) termination to connect external measuring impedance in a compact design.
It is optimized for measuring partial discharges together with the PD detector DDX 9160 or 9161 (optimally using internal (built-in) measuring impedance (AKV)).
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 overvoltage by a mechanical spark-gap.
