What are the related functions of the ratio group tester?

During the production process of semi-finished and finished products of power transformers, before the newly installed transformers are put into operation, and according to the preventive test procedures of the State Grid, it is required to regularly test the turns ratio or voltage ratio of the operating transformers. The traditional ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions must be performed. The test result is only the value of one phase ratio. This TKBB transformer ratio tester overcomes the shortcomings of traditional ratio bridge testing. The screen uses a large-screen high-resolution LCD display, which is convenient for on-site use. It has a Chinese menu prompt function, is easy and intuitive to operate, and completes the three-phase ratio test at one time. The test speed is fast and the accuracy is high.

Transformation ratio group tester function

1 Full three-phase sinusoidal inverter power output, automatic output voltage adjustment, with soft start and soft stop functions, so the test speed is fast and the accuracy is high.

2 Three-phase transformer, single-phase transformer, PT, Z-type transformer ratio, group, polarity test function.

3 It has a blind test function, that is, it can perform ratio and group tests when the high and low voltage connection methods are unknown.

4 CT ratio polarity test function.

5. It has the function of angle difference test during single-phase test.

6 The maximum tapping position can be tested is 197.

7. Wide test range, up to 10000.

8. High and low voltage reverse connection protection function.

9 Output short circuit protection function.

10. Clock and date display without power failure; data storage methods include local storage and USB storage, where the local storage can store 500 test data, and the local storage can be transferred to the USB flash drive; the data format of the USB flash drive is Word format, which can be directly edited and printed on the computer.

11 Thermal printer printing function, fast and silent.

12 Small size, light weight, easy to carry and use.
