Vanguard EZCT-10 current transformer tester
 

Overview

Vanguard 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.
