For Voltage Transformer (VT) tests:
- Checking the electrical performance of VTs.
- Assessing the state of VTs.
- Tests such as ratio, phase, polarity, capacitive ratio.
Additionally, for accuracy verification and calibration of the voltage transformer (VT/VTC):
- Verification of accuracy class according to IEC, IEEE.
- Testing VTs up to nominal voltages and up to 1.9 voltage factor.
- Assessment of accuracy class.
- Accuracy classes up to 0.1 for VTs.
