Testing Application Notes (PowerPoint Presentation)

The EZCT-2000B is Vanguard’s third-generation microprocessor-based current transformer test set. Designed specifically for CT testing, the EZCT-2000B 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 secondary burden

The EZCT-2000B’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
  • RS-232C, USB, USB Flash drive interface
