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.


The Vanguard EZCT-10 is a microprocessor-based, portable current-transformer test set. This rugged test set can perform the current transformer (CT) excitation, CT current-ratio, and winding polarity tests. 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-10 uses a heavy-duty transformer to perform the CT excitation test. It is capable of outputting 50 VAC at 10A and 200 VAC at 10A.
