JYH-B instrument transformer characteristic tester can measure the turns ratio, polarity and volt-ampere characteristics of the current transformers and voltage transformers. It has large power regulating transformer, step-up transformer and current-up device inside. The tester is widely used in the routine test of voltage and current transformers.
