The AKV 9330 has been specially designed for Partial Discharge (PD) testing of power capacitors. It addresses two major problems associated with large capacitor PD testing – reduced measurement sensitivity and high current requirements. By a new approach, AKV 9330 amplifies the PD measuring sensitivity significantly while simultaneously handling power frequency currents up to 300 A. It is an ideal IEC 60270 – compliant solution for PD testing of power capacitors.

Advantages
• High sensitivity for PD measurement – In comparison with other quadripoles the AKV 9330 provides the highest sensitivity for the PD testing of large power capacitors, thanks to the unique and specific design.
• Easy to integrate into test systems.
• Optimized for the complete spectrum of power capacitors (from LV to MV (HV) range)
• The built-in overvoltage protection will protect the PD detector in case a flash in the test object would happen during the test.
• Fulfils the IEC and ANSI standards

Applications
• Power capacitors (LV, MV, HV)
• Research and development
