The Model EZCT-10 is a microprocessor-based, current-transformer test set. This rugged and portable test set measures excitation current, turns ratio and winding polarity on single- and multi-ratio current transformers. Current transformers can be tested in their field-mounted configuration, eliminating the need to remove bushings or current transformers from the host equipment.
The EZCT-2000A is Vanguard’s third-generation microprocessor-based current transformer test set. The EZCT-2000A can perform the current transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically. All of the EZCT-2000A’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-2000A without any operator intervention.

Fully Automated
Test record header information including company, substation name, circuit ID, manufacturer, CT serial number, operator name, and test record-comments
The EZCT-2000C Plus 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 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
The EZCT S2A is Vanguard’s third-generation, microprocessor-based, current transformer test set. The EZCT S2A can perform the current transformer (CT) excitation, CT current-ratio, and winding polarity tests automatically. The EZCT S2A automatically raises and lowers the excitation test voltage without any operator intervention. With up to 1500 Vac excitation test voltage available, the EZCT S2A can easily perform excitation tests on very large CT’s.
