Detailed Product Description:
The digital ratio tester is designed to solve the problems of using a ratio bridge to measure transformer ratio, which is cumbersome and has a narrow measurement range, no longer meeting the fast-paced and high-efficiency requirements of modern measurement. For this reason, our company has adopted modern electronic technology to develop a new generation of ratio and group tester. It features small size, light weight, high accuracy, stable performance, menu operation, and user-friendly interface. It can measure the ratio/group of various transformers in one go.
With a microcontroller as the core for measurement calculation and automatic control,the full Chinese menu operation interface has the advantages of intuitive display, good stability, high accuracy, wide measurement range, and no need for three-phase power supply on site.
It can measure the ratio and connection group of various three-phase transformers, and also measure the transformation ratio and polarity of single-phase transformers and voltage transformers. It can display ratio error and has data printing function.
