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 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
- High precision 0.3%
- Precision for protection 3P
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 plugs in gas-insulated switchgears, series 12 kV or 24 kV
- Voltage amplifier type CAPDIS-4o
