Tranformer Turn Ratio Tester

In the semi-finished transformers and the finished the transformers production process, before the newly installed transformers being put into operation, and according to the preventive tests of the Ministry of  Electric Power, the Turns and ratio of the transformers should be tested periodically. The traditional variable ratio electric bridge operating is cumbersome, and not intuitive for readings. It also needs to carry out the necessary conversion. The test results only for the information of one phase transformation ratio. TRT-V Automatic Transformer Turns Ratio Meter overcome the traditional variable Bridge Test shortcomings. A big screen used lattice liquid crystal monitor, with menu suggested function. The operating is simple and intuitive. It can complete a three-phase variable ratio testing .Fast testing speed and high accuracy rate.

1) Test range wide, the highest can reach up to 10000.
2) Fast test speed, seven seconds of the completion of single-phase testing.
3) Z-shaped connection transformer testing.
4) Blind test variable ratio, groups functional testing.
5) Not power off of the clock and date display, data storage functionality.
    It can save 50 groups test datas. 
6) High and low pressure reverse protection function.
7) Transformers short circuit and inter-turn short circuit protection function.   
8) Thermal printers output function, quick and silent. 
9) AC/DC dual power supply, suitable for working at site.
10) Display 240*128,Intuitive interactive interface.
11) Small size, light weight.
