Measuring impedances (also known as quadripoles) are used for the decoupling of PD current pulses placed in series with a coupling capacitor in standard measuring circuits to convert into voltage pulses for analysis with a PD detector according to IEC 60270. An additional voltage signal output allows for the voltage measurement and synchronization of the applied test voltage for phase-resolved measurements.
Measuring Impedance Models:
|Fixed low voltage capacitance (max. 3 A):||AKV 9310|
|Switchable low voltage capacitance (max. 6 A):||AQS 9110a|
|For large power capacitors (max. 300 A):||AKV 9330|
