EZCT-2000C
Automated 2 kV Current Transformer Test Set with IRM and Burden Tests
Increases productivity & saves time during commissioning
The EZCT-2000C is Vanguard’s third-generation microprocessor-based current transformer test set. Designed specifically for CT testing, the EZCT-2000C has the following outstanding features that can greatly increase productivity and save time during the commissioning stage:
- Performs CT excitation, current-ratio, polarity, and phase angle tests
- Measures insulation resistance and winding resistance of the CT secondary windings
- Measures the CT’s load burden
- Standalone or computer-controlled via USB or Bluetooth wireless interface
The EZCT-2000C’s test leads can be connected to all the CT output terminals, and the complete CT test can be performed automatically without any operator intervention.
