Product Introduction
The transformer ratio tester is an intelligent transformer ratio testing instrument developed according to the GB1094-79 standard. The automatic transformer ratio tester has the characteristics of small size, light weight, simple operation, convenient reading, good stability, high accuracy, wide measurement range, and high degree of automation in the measurement process. It can directly measure the group, transformer ratio value, and ratio error value of single-phase and three-phase transformers and mutual inductors. At the same time, it can automatically print, making it an ideal testing device for power departments.The automatic transformer ratio tester has the characteristics of small size, light weight, simple operation, convenient reading, good stability, high accuracy, wide measurement range, and high degree of automation in the measurement process.
