Description
The CT-T1 is a microprocessor-based Current Transformer Tester that measures CT excitation current, turns ratio, and winding polarity tests, all without having to switch the leads during testing. The instrument has a fully automatic knee point detection (ASA 10/50, IEEE 30°, IEEE 45°). Although includes 5 low side taps and 1 high side tap.
This CT Tester is precision-made, just like all of the Raytech products you already know.
