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.
Ratio and Polarity Test
The EZCT-10TM determines the current-transformer turns ratio by accurately measuring the voltages across the primary and secondary windings (a direct proportion) and then displaying the voltage ratio. Turns ratio is measured from 0.8 through 5,000 to 1.0 with an accuracy of 0.5% or better. Winding polarity displays as a + or - sign and is also annotated with the phase in degrees.
