Current Transformer Test Set
MODEL: EZCT-2000C
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.
FEATURES & BENEFITS

- 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

EZCT-2KA Current Transformer Test Set
MODEL: EZCT-2KA
The EZCT-2KA is Vanguard’s third-generation microprocessor-based current transformer test set. The EZCT-2KA can perform the current transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically. All of the EZCT-2KA’s test leads can be connected to the CT output terminals (X1, X2, X3, X4 and X5), eliminating the need for lead switching during testing. Test voltage output is automatically raised and lowered by the EZCT-2KA without any operator intervention. With up to 2000 Vac excitation test voltage available, the EZCT-2KA can easily perform excitation tests on very large CT’s.
FEATURES & BENEFITS
- Perform Saturation, Ratio and Polarity Tests
- Perform CT Winding Resistance Test
- Fully Automated
- Test record header information including company, substation name, circuit ID, manufacturer, CT serial number, operator name, and test record-comments
- Plot Multiple Saturation Curves
- Store 1,000 Records (Each test record may contain up to 10 sets of excitation, resistance, and ratio data)
- USB and Bluetooth computer interface
- USB Flash drive interface
- Furnished with full set of test leads
PART NUMBERS
- 9118-UC [110V]
