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.

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.

  • Perform Saturation, Ratio and Polarity Tests
  • Fully Automated
  • Comprehensive Graphic and Tabulated Test Reports
  • Plot Multiple Saturation Curves
  • Store 64 Records (of 10 Saturation Curves)
  • Computer Interface

  • 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

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.

  • 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
