CPL 542/543

Measuring impedance – accessory for partial discharge measurement products

The CPL quadripole is an external measuring impedance for partial discharge measurements.

The frequency diplexer separates the PD measurement signal and the test voltage to the PD and V outputs. Connected measurement equipment is reliably protected from dangerous overvoltages, which prevents costly failures.

Measurement equipment can be synchronized to the test voltage via the V output. Three different quadripoles are available from 0.5 A to 5 A to cover most measurement tasks.

Key features

  • Protection from voltage peaks and current surges
  • Optimized frequency response
  • Separated output for breakdown detection
