Testing Application Notes (PowerPoint Presentation)

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
