First, the main function

HGY volt-ampere characteristics, ratio, polarity tester is specifically designed for relay protection test current transformer volt-ampere characteristics, variable ratio test and polarity discrimination design, but also for the transformer polarity test, is a Performance and low cost, relatively high multifunctional test equipment.
The instrument uses high efficiency and low consumption of high-quality materials and special around the booster, the microprocessor for data acquisition, analysis and storage, built-in micro-printer can print test data and curves, measured CT ratio, can automatically calculate the ratio . This machine is light weight, portable, easy to operate, its unique performance, is a rare instrument.
