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