Product Description

Product Description

According to IEC and relevant national standards, in the production of power transformers, the user handover and maintenance test process, the transformer ratio test is a mandatory project. This can effectively supervise the quality of transformer products in the factory and in the process of use, to prevent transformer turn-to-turn short-circuit, open circuit, connection error, regulator switch internal failure or contact failure. My company independent development, research and production of multifunctional handheld automatic ratio tester in addition to have completely according to the user's on-site use requirements, easy to operate, complete functions, data stability and reliability of the characteristics of the domestic so far, or the first can be carried out to the full blind test (do not know any parameter of the transformer to be tested under the circumstances of the accurate measurement of the ratio value and the group number) of the ratio tester; to adapt to the needs of a variety of large and small transformer ratio test, and to adapt to the needs of a variety of large and small transformers. Transformer ratio test needs, is so far the domestic ratio test in the very advanced technology, test program is very perfect, comprehensive measurement parameters of the ratio tester.
Instrument built-in large-capacity lithium-ion rechargeable battery, without external power supply can be tested, the site is convenient and easy to use.

The instrument adopts large screen true color LCD as the display, full Chinese graphical operation interface and equipped with Chinese character prompting information, multi-parameter display LCD interface, friendly man-machine dialogue interface, vector diagram display and wiring judgment for checking the correctness of the circuit provides a reliable basis. Full touch conductive silicone keyboard operation mode, operation feel good, easy to use. Instrument built-in high-capacity power-down not lost data memory, can be saved on-site calibration data, up to 1000 groups of extended storage site calibration results, can provide background microcomputer management software, through the U disk will be the results of the transfer to the computer, production reports, printing, to achieve microcomputerized management.

The instrument adopts the engineering plastic shell which is independently designed and molded by the company, and the appearance of the instrument is beautiful and practical. It is easy to operate on-site testing.
 

Product Features

1. The real three-phase test: single-phase power input, internal digital synthesis of three-phase standard sine wave signal source, through the high-fidelity power amplifier, resulting in three-phase test power (distortion is less than 0.1%, symmetry is better than 0.05%) output, the test results have a better equivalence, will not appear group misjudgment and other phenomena.

2. Powerful function: both single-phase measurement, but also can realize the three-phase winding automatic test, single-phase, three-phase can be measured polarity, one time to complete the measurement of AB, BC, CA three-phase ratio value, error, tap position, tap value and other parameters, can automatically identify the group number (0-11 is equivalent to 1-12).

3. Hexagonal diagram display function: the test results are displayed in digital and hexagonal vector diagrams, which intuitively shows the transformer connection group.

4. Blind test function: no need to select the wiring mode, no need to select the wiring group, measuring Y / △, △ / Y transformer without external shorting, according to the selection of the test content can automatically switch the wiring mode. Completely can be no nameplate transformer ratio and group number measurement.

5. Tap test: can quickly measure in each tap changer position ratio and ratio error, rated ratio only need to input once, do not have to repeatedly input can be calculated in each tap position of the ratio error.

6. At the same time with turns ratio measurement and running voltage ratio measurement of two functions, running ratio can more truly reflect the transformer in the actual operation of the actual value of the voltage ratio.

7. Good vibration resistance: the use of connectors to enhance the anti-vibration performance.

8. The use of 5-inch high-definition true color LCD screen, display data effect and vector diagram effect intuitive and delicate.

9. The test source used in this instrument is a digitally synthesized standard sinusoidal digital source, the distortion is less than 0.1%, not affected by the quality of the working power supply.

10. Easy to carry: small size, light weight.    

11. The internal equipped with high-capacity lithium-ion rechargeable batteries, the site can complete the test without any power supply, a full can be more than 500 consecutive measurements.
