9101-UC [110V]
9102-UC [220V]
9101-SC [Shipping Case]

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.

  • Performs CT excitation, current-ratio, polarity, and phase angle tests
  • Measures insulation resistance and winding resistance of the CT seconday windings
  • Measures the CT's secondary burden
  • Test record header information including company, substation name, circuit ID, manufacturer, CT serial number, operator name, and test record-comments
  • Built-in 4.5-inch wide thermal printer
  • Plot Multiple Saturation Curves
  • Stores up to 128 CT test plans and 140 test records internally
  • USB, Bluetooth, and USB Flash drive interface
