The AKV 9360 is a measuring impedance (sometimes also called coupling device or quadripole). It is a fully passive and optimized for use with the DDX 916x series of partial discharge detectors. The AKV 9360 splits and condition the partial discharge high-frequency signal and HV test voltage signal (power frequency). It serves as well as a surge and over-voltage protection. It is equipped with an internal voltage divider and a dedicated 4 mm output connector for an external low-arm device. It fulfils the NEMA and CISPR requirements for the RIV measurement. It can be optionally equipped with a secondary low-arm resistance allowing measuring the DC voltage (AKV 9360DC).
AKV 9360-SEK provides combination of the measuring impedance and calibrated voltage secondary measuring unit (SEK).

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.
• 2 in 1 solution reduces connections and space
