The AKV 9310 series of quadripole (measuring impedance) is a fully passive measurement system optimized for use with the DDX 9121b series of partial discharge detectors. The AKV 9310 quadripole is designed for simultaneous measurement of high-frequency discharge pulses as well as the HV test voltage. The AKV 9310 series of quadripole 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).

Advantages
• No batteries or charger needed.
• Easy to integrate into test systems.
• Brings the synchronization and voltage measurement signal to the PD detector.
• The built-in overvoltage protection will protect the PD detector in case a flash in the test object would happen during the test.

Applications
• Power and distribution transformers.
• Instrument transformers.
• Rotating machines.
• Switchgears (MV/HV/GIS)
• Surge arresters
• Bushings
• Cables
• Power capacitors
• Components testing
• Research and development
