Product details
Product IntroductionProduct Introduction
According to IEC and relevant national standards, transformer ratio test is a necessary item in the production, user handover, and maintenance testing of power transformers. This can effectively supervise the quality of transformer products during production and use, prevent inter turn short circuits, open circuits, connection errors, internal faults or contact faults of the voltage regulating switch. Our company's independently developed, researched, and produced multifunctional desktop fully automatic 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 ratio tester in China that can accurately measure the ratio value and group number without knowing any parameters of the tested transformer, and can accurately measure the phase angle; It can adapt to the needs of various large, medium and small transformer ratio tests (including Z-type transformers, rectifier transformers, electric furnace transformers, non integral phase-shifting transformers, balance transformers, Scott and inverse Scott transformers), and is currently a highly advanced technology in domestic ratio testing. The testing items are very complete, and the measurement parameters are comprehensive.
The instrument is equipped with a large capacity lithium-ion rechargeable battery, which allows for testing without the need for an external power source, making it convenient and easy to use on site.
The instrument has a complete protection function, and the output test source automatically detects the load current and provides corresponding protection, stops the test and gives a prompt, without causing damage to the instrument due to external test circuit overload or short circuit.
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 use. The instrument is equipped with a large capacity built-in power failure data storage, which can save on-site verification data and can expand the storage of up to 1000 sets of on-site verification results. It can provide backend microcomputer management software, which can transfer the results to the computer through a USB flash drive, produce reports, print, and achieve microcomputer 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.

Product FeaturesProduct Characteristics
-
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, generates three-phase test power output (distortion less than 0.1%, symmetry better than 0.05%), the 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. Both single-phase and three-phase can measure polarity and phase angle. It can complete the measurement of AB, BC, CA three-phase transformation value, phase angle value, error, tap position, tap value and other parameters in one go, and can automatically identify the group number (0-11 is equivalent to 1-12).
-
3. Phase angle measurement function: Accurately measure the phase angle (0-360 °) between the high and low voltage sides, and can measure the transformation ratio and angle of non integer point transformers.
-
4. Hexagonal diagram display function: The test results are displayed in numerical and hexagonal vector diagrams, which intuitively show the connection group of the transformer.
-
5. 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. It is entirely possible to measure the transformation ratio and group number of transformers without nameplates.
-
6. 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.
-
7. At the same time, it has two functions: measuring the turns ratio and measuring the operating voltage transformation ratio. The operating transformation ratio can more accurately reflect the actual value of the voltage transformation ratio of the transformer in actual operation.
-
8. Good anti vibration performance: The use of military connectors enhances the anti vibration performance.
-
9. Adopting a 5-inch high-definition true color LCD screen, the display of data and vector graphics is intuitive and delicate.
-
10. The instrument comes with a thermal sensitive high-speed micro printer, which can print and retain the test results at any time
-
11. 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.
-
12. Convenient to carry: small size and light weight.
-
13. Equipped with high-capacity lithium-ion rechargeable batteries internally, the testing work can be completed on site without any power supply. With one full charge, it can perform more than 500 consecutive measurements.
