VT Analyzer

The first portable device (15 kg/33 lbs) which offers highly accurate voltage transformer tests.

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

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
