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

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.
  • 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 140 Records (of 10 Saturation Curves)
  • Computer Interface
  • USB Flash drive interface
