Product Interview:
In the production process of semi-finished products and finished products of power transformers, before the newly installed transformers are put into operation, according to the precautionary test regulations of the State Ministry of Electricity, it is required to test the turn ratio or voltage ratio of the transformers in operation regularly.
Main Features:
1.The range of measurement is wide and the ratio can be measured up to 10 000
2.Built-in three-phase digital power supply to improve test stability
3.Small size, light weight, fast test speed, complete three-phase test in 10 seconds
4.Testing of connected transformer
5.It has the functions of bd variable ratio test and group test
6.No power-off clock and date display, data storage function (optional to save data to U disk)
7.High and low voltage reverse connection protection and short circuit protection functions
8.Thermal printer output function, fast speed,low noise
9.Full-transparent large-screen liquid crystal can be clearly displayed in the sun
