AKV 9310
The AKV 9310 is a measuring impedance (sometimes also called coupling device or quadripole). It is a fully passive and optimized for use with the DDX 9121b partial discharge detector.

The AKV 9310 is designed for simultaneous measurement of high-frequency discharge pulses as well as the HV test voltage.
The AKV 9310 series is equipped with an internal voltage divider and a dedicated 4 mm output connector for an external low-arm device.
It can be optionally equipped with a secondary low-arm resistance allowing measuring the DC voltage (AKV 9310DC) or tuned with a specific CISPR requirements for the RIV measurement (AKV 9310RIV).
