CAPDIS-4o_HF
Voltage transformer replacement for ohmic voltage sensors
with burden resistance 200 kOhm for sensors from Zelisko
Part-No.: 2502073_H002
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
High device class accuracy
The device class accuracy is 0.5%. Higher accuracy on request.
