HV Equipment

AKV 9310 (Up to 3 A)


The AKV 9310 series of quadripole (measuring impedance) is a fully passive measurement system optimized for use with the DDX 9121b PD detector. The AKV 9310 is designed for simultaneous measurement of high-frequency discharge pulses as well as the HV test voltage. It is equipped with an internal voltage divider and a dedicated 4 mm output connector for an external low-arm device.

The AKV 9310DC model includes an internal RC divider to allow for DC partial discharge testing.


  • Designed for PD and RIV measurements
  • Easy to connect
  • High input current up to 3 A
  • Fixed internal voltage divider
  • Output for external low arm voltage measurement (floating connection)
  • Passive coupling impedance: no batteries or charger needed
  • Model for DC PD testing available (AKV 9310DC)
  • Measuring band exceeds the requirements of IEC 60270
  • Built-in over-voltage protection
  • Internal voltage divider delivers the synchronization and voltage measurement signal to the PD detector for phase-resolved measurements
  • Easy integration or replacement into existing test system due to its compact design, standard BNC outputs, and grounded/floating switch
