According to IEC and relevant national standards, transformer ratio test is a must in the process of power transformer production, user handover and maintenance test. This can effectively supervise the quality of transformer products before delivery and in the process of use, to prevent short circuit, open circuit, connection error, internal fault or contact fault of voltage regulator switch. My company independent development, the development and production of variable thewire tester besides completely according to the requirements of the user field use, easy to operate, fully functional, data is a stable and reliable characteristics could be blind test (don't know any nameplate parameters of the transformer under test under the condition of accurate measurement variable ratio and group number, and can accurately measure the phase Angle) of the variable thewire tester; It can adapt to various requirements of transformer transformer ratio test (including z-type transformer, rectifying transformer, electric furnace transformer, non-hour shift phase change, traction transformer, Scott and reverse Scott transformer), and is a variable ratio tester with advanced technology, perfect test items and comprehensive measurement parameters in domestic transformer ratio test so far.
Variable ratio tester adopts large-screen true-color liquid crystal as the display, and the whole English graphical operation interface is equipped with English character prompt message and multi-parameter display liquid crystal display interface. Human-machine dialogue interface is friendly, vector diagram display and wiring judgment provide a reliable basis for checking the correctness of the circuit. Full touch conductive silicone keyboard operation mode, operation feel good, easy to learn. Variable ratio tester built-in large capacity power loss without loss of data storage, can save on-site verification data, can expand storage of up to 1000 groups of on-site verification results, can provide background microcomputer management software, through the U disk to transfer the results to the computer, production report, printing, realize microcomputer management. Variable ratio tester adopts the engineering plastic shell independently designed and moulded by our company, and the appearance of the instrument is beautiful and practical. Field test is easy to operate.

1、It is especially suitable for transformer ratio and phase difference test
2、It is especially suitable for the measurement of rectifying transformer with phase shift
3、A three-phase (120°) or two-phase (90°) power supply with stable amplitude and constant phase is automatically produced
4、The voltage ratio and phase Angle difference of the high and low voltage side are measured directly without the restriction of the internal wiring mode of the transformer
5、Real simultaneous measurement of three phases
6、The test parameters can be set at one time, and the tap switch can be directly tested after conversion to automatically judge the tap position and the standard change ratio after conversion
7、Fast, the test time for a set of data is 8 seconds
8、The test results are not affected by the fluctuation of power supply frequency and amplitude
9、Internal overcurrent protection function, high and low voltage reverse connection protection function
10、The upper computer can control the whole test process, save the data and print the test report
11、Test results automatically saved, up to 99
12、The built-in manual of variable ratio tester can be checked at any time
