Voltage transformer replacement for medium-voltage switchgears

 

Description

The CAPDIS-4o amplifier provides an output voltage of 3 x 100 VAC /sqrt (3) in combination with three ohmic coupling electrodes as sensors. The amplifier can therefore be used as a replacement for three inductive voltage transformers.

  • economic alternative to voltage transformers in feeders
  • minimum space requirement, no additional measuring field required
  • no disassembly required for surge stress tests
  • no ferroresonance risk

Extra features

  • High frequency version, cut-off frequency 2 kHz
  • 200k burden for e.g. Zelisko sensors

High device class accuracy

The device class accuracy is 0.5%. Higher accuracy on request.

 

Universal system components

  • ohmic divider type OKE for air-insulated switchgears, series 12 kV, 24 kV or 36 kV
  • ohmic divider type OAS for angle plug in gas-insulated switchgears, series 12 kV or 24 kV
