Prevent inter turn short circuits, open circuits, incorrect connections, internal faults or contact faults in the voltage regulating switch of transformers. Our company's independently developed, researched, and produced multifunctional fully automatic transformer ratio tester not only has the characteristics of completely meeting the user's on-site usage requirements, easy operation, complete functions, and stable and reliable data, but also is the first transformer ratio tester in China that can perform blind testing (accurate measurement without knowing the connection method and group of the tested transformer) and test the parallel operation status of the main transformer; The testing problem of parallel operation of transformers from the root can meet the needs of various large, medium and small transformer ratio tests. It is currently the most advanced technology, most complete testing items, and most comprehensive measurement parameters transformer ratio tester in China.

The instrument adopts a large screen true color LCD as the display, with a fully Chinese graphical operation interface and a LCD display interface with Chinese character prompt information and multi parameter display. The human-machine dialogue interface is friendly, and the vector diagram display and wiring judgment provide a reliable basis for checking the correctness of the circuit. The fully touch conductive silicone keyboard has a good operating feel and is easy to learn. The instrument is equipped with a large capacity built-in power failure memory that does not lose data. It can save on-site verification data and can expand to store up to 1000 sets of on-site verification results. It can provide backend microcomputer management software to upload the results to the computer for computerized management.

The instrument adopts an engineering plastic shell independently designed and manufactured by our company, which has a beautiful and practical appearance. The on-site testing operation is convenient.

1. True three-phase testing: single-phase power input, internal digital synthesis of three-phase standard sine wave signal source, through high fidelity power amplifier, generating three-phase test power supply (distortion less than 0.1%) output, test results have better equivalence, and there will be no group misjudgment or other phenomena;

2. Powerful function: It can perform single-phase measurement and automatic testing of three-phase windings. Polarity and phase angle can be measured for both single-phase and three-phase, and the transformation value, error, tap position, tap value and other parameters of AB, BC, CA phases can be measured at once. The group number can be automatically identified;

3. Blind testing function: No need to select the wiring method or wiring group, measuring Y/△ and △/Y transformers does not require external short circuiting, and the wiring method can be automatically switched according to the selected testing content;

4. Tap test: It can quickly measure the transformation ratio and transformation ratio error at each tap switch position. The rated transformation ratio only needs to be input once, and the transformation ratio error at each tap position can be calculated without repeated input;

5. Good anti vibration performance: The use of military connectors enhances the anti vibration performance;

6. Revolutionary representation of the magnitude and phase relationship between various voltages and currents using vector graphics, making it easier for users to subjectively understand the actual meaning of each parameter;

7. Adopting a 7-inch high-definition color screen to display data effects and vector graphics with intuitive and delicate effects;

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

9. Convenient to carry: small size, light weight;

10. Optional internal rechargeable battery, no power supply required on-site to complete testing work;
