Voltage Amplifiers For Getting Voltage Transformer Output in the Grid System
Voltage transformer replacement for medium-voltage switchgears
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
There is no ferroresonance failure as voltage transformers (no resonance due to the capacity of the line and the impedance of the inductive voltage transformer)
Burden resistance 200 kOhm for sensors is optional.
Data sheet can be seen in addition.
