According to IEC and related national standards, in the power transformer production, user acceptance and maintenance test process, the transformer ratio test is will do the project, which can effectively supervise transformer products factory and using in the process of quality, prevent transformer interturn short circuit, open circuit, connection error, pressure regulating switch is in an internal fault or contact failure. Therefore we developed production SDBB-II automatic ratio tester on the basis of the original according to the user's site requirements, and the operation is more convenient, complete function, stable and reliable data, test speed is greatly improved. To meet the needs of all kinds of small medium and large transformer test.

First, pay attention to matters

1, please read the instructions carefully before use.

2, the instrument indoor and outdoor can be used, but should avoid heavy rain, corrosive gas, dust, high temperature, sunlight and other places.

3, when the connection of the high voltage side and the low voltage side can not be connected to the side.

4, after the instrument can not be the test leads to each other short circuit or grounding, etc., must be handled without the wire clip.

5, the instrument wiring should pay attention to yellow, green, red three color, respectively, corresponding to the transformer A, B, C, three-phase terminal, can not be wrong.

6, the maintenance of the instrument, the adjustment should be carried out by professional personnel.

1, Chinese menu prompt, simple and convenient operation.

2, the ratio of large measurement range: 1-10000

3, the function is powerful: both single phase measurement, and can realize the automatic test of the three-phase winding. Join groups can be arbitrary choice, a complete measurements of AB, BC, CA three-phase variable ratio, error, line group and other parameters.

4, measuring speed. (three - phase simultaneous detection of only ten seconds)

5, once the measurement is completed, automatic cut off test power.

6, set the data, the measurement results automatically saved, you can view the previous data.

7, test load transformer, only an input ratio.

8, easy to carry, suitable for field work.

1, ratio measurement range: 1-10000.

2, accuracy: 1-1000 0.2% 1000-10000 0.5%.

3, power supply: 220V + 10%, 50HZ.

4, group: 1-12

5, working temperature: 0-40.

6, relative humidity: less than 80% no dew.
