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. The amplifier can therefore be used as a replacement for three inductive voltage converters.

  • 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

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
  • Voltage amplifier type CAPDIS-4o
