VT Analyzer
Sophisticated testing of inductive and capacitive voltage transformers
The first portable device (15 kg/33 lbs) which offers highly accurate voltage transformer tests.
How VOTANO 100 works
- Uses a well-established, model-based testing method
- The method can be compared to that used by OMICRON’s CT Analyzer
- Injects low test signals into the secondary side of a VT/CVT
- Determines a VT’s/CVT’s equivalent circuit parameters
- Identifies all relevant VT/CVT performance parameters
- Displays all relevant VT/CVT parameters and its accuracy at different currents and burdens and with loaded and unloaded secondary windings
- Evaluates the VT/CVT according to the selected standard
Key features: For voltage transformer testing (VT/CVT):
- Check the electrical performance of VTs and CVTs
- Check the condition of VTs and CVTs
- Basic condition assessment for CVTs
- Tests such as ratio, phase, polarity, capacitive ratio
- Additionally, for voltage transformer accuracy verification and calibration (VT/CVT):
- Verify accuracy class according to IEC, IEEE
- Test of VTs/CVTs up to rated voltages and voltage factors up to 1.9
- Class assessment
- Accuracy classes up to 0.1 for VTs and 0.2 for CVTs
