Keeping transformers operational requires regular testing to prevent power interruption and possible damage to electrical equipment systems. When transformers fail, it can often be due in part to heat exposure over long periods of operational time. By scheduling a system of regular diagnostic testing for transformers, problems are detected early thus helping to extend the life of this important equipment while also reducing the chance of accidents.

The EZCT-2000C Plus Automated CT Test Set is Vanguard’s third-generation microprocessor-based current transformer test set. Designed specifically for CT testing, the EZCT-2000C Plus 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 Plus’ test leads can be connected to all the CT output terminals, and the complete CT test can be performed automatically without any operator intervention.
