Comprehensive Transformer Characteristics Tester
Comprehensive Transformer Characteristics Tester is specially designed for relay protection professionals to test the volt-ampere characteristics of current transformers, ratio testing, and polarity discrimination. It can also be used for transformer polarity discrimination testing. It is a multifunctional test instrument with a high performance-to-price ratio.
This instrument adopts high-efficiency, low-consumption high-quality materials and specially wound voltage boosters, with a microcontroller microprocessor for data acquisition, analysis, and storage. It has a built-in micro printer that can print test data and curves. When measuring CT ratio, it can automatically calculate the ratio value. One person can complete all test work. This instrument is lightweight, easy to operate, and has unique performance, making it an indispensable tool for field personnel.
