Measuring impedance CD-2
Measuring impedance for decoupling of Partial Discharge signals
- Decoupling of PD current pulses through the coupling capacitor in standard measuring circuits and converting into voltage pulses to transfer to a PD measuring instrument
- Additional signal output for voltage measurement and syncronization with the test voltage for phase resolved measurements
- Voltage output with a fixed low voltage capacity (CD-1) or switchable to different capacities (CD-2) possible
- Signal bandwidth of the transformer > 20 MHz at 50 Ω, lower cut-off frequency < 100 kHz
- Built-in over-voltage protection circuit
- Grounding with robust clamping rail or jack
