PS-BB101A Handheld Three-Phase Transformation Ratio Tester

Short Description:

The power transformer shall be regularly tested for turns ratio or voltage ratio, including semi-finished products and finished products in the production process, transformers before putting into operation and during operation in the power system. The traditional transformation ratio bridge is cumbersome to operate, the reading is not intuitive, the necessary conversion is needed, and the test results only reflect a phase transformation ratio. The instrument overcomes the shortcomings of the traditional transformation ratio bridge test, completes the three-phase transformation ratio test at one time, has fast test speed and high accuracy, and greatly improves the test efficiency.

Model No.: PS-BB101A

Safety Measures

1 Be sure to read the operating instructions carefully before using the instrument.

2 The instrument can be used indoors and outdoors, but it should avoid the environment of rain, corrosive gas and dust.

3 The instrument shall avoid violent vibration.

4 The maintenance, nursing and adjustment of the instrument shall be carried out by professionals.

5 The yellow, green and red of the test clamp correspond to A/a, B/b and C/c of the transformer respectively. Do not connect them incorrectly.

6 Do not connect the high and low voltage test lines reversely.

7 When measuring single-phase transformer, only yellow and green lines are used, and the red test line is not connected (or suspended).
