Comprehensive Transformer Characteristics Testing Instrument
Comprehensive Transformer Characteristics Testing Instrument is specifically designed for relay protection professionals to test current transformer volt-ampere characteristics, ratio testing, and polarity discrimination. It can also be used for transformer polarity discrimination tests, making it a multifunctional testing instrument with a high performance-to-price ratio.
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 ratio, it can automatically calculate the ratio value. A single operator can complete all testing tasks. This instrument is lightweight, easy to operate, and unique in performance, making it an indispensable tool for field personnel.
