XHBB128ATransformation ratio tester

Description

During the production process of semi-finished products and finished products of power

transformers, before the newly installed transformers are put into operation and in accordance with

the preventive test procedures of the National Electric Power Ministry, it is required that the

transformers in operation be regularly tested for the turns ratio or voltage ratio. The traditional

variable bridge operation is cumbersome, the reading is not intuitive, and the necessary conversion

is performed. The test result is only a phase change ratio. The automatic ratio change tester

overcomes the shortcomings of the traditional turn ratio test. The instrument completes the

three-phase ratio test at a time, and the test speed is fast and the accuracy is high.

Features:

1). The test range is wide, up to 5000.

2).Test speed is fast, 7 seconds to complete the three-phase test

3) .Z-connected transformer test.

4). The clock and date display even power is off, data storage.

5). High and low voltage reverse connection protection function.

6). Transformer short circuit, inter-turn short circuit protection.

7). Thermal printer output function, fast, silent.

8). Equipped with RS232, USB interface, easy to connect to the computer to export data.

9). Small size and light weight.
