Transformer Tester

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 features that can increase productivity and save time during the commissioning stage of circuit breakers and transformers:

  • 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 test leads can be connected to all of the CT output terminals, and the complete CT test can be performed automatically without operator intervention. The CT saturation test is performed using the ANSI/IEEE C57.13.1 test method. The output voltage ranges from 50 Vac to 2000 Vac, and the current ranges from 1 A to 10 A. The EZCT-2000B has a programmable current source (0-20 A, 0-15 Vac) that can be used to verify CT loads. The on-time timer and output current are displayed on the LCD screen. This unit stores up to 140 test records (10 tests per record) and 128 CT test plans. Test records and test plans can be transferred to a PC using the RS-232 port, USB port, and USB Flash Drive port.
