MIBC-VI Transformer Ratio Tester

MIBC-VI Transformer Ratio Tester

Product Introduction

MIBC-VI Transformer Ratio TesterThe built-in rechargeable battery is used for measuring the turns ratio or voltage ratio of power transformers and voltage transformers, and can meet the requirements of preventive testing regulations for transformers.
according toIECAccording to relevant national standards and regulations, transformer ratio testing 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 fully automatic variable ratio tester not only hasAccording to the on-site usage requirements of users, this transformer ratio tester is characterized by easy operation, complete functions, and stable and reliable data. It is also the first in China that can perform blind testing (accurate measurement without knowing the connection method and group of the tested transformer) to test the parallel operation status of the main transformer; Testing the parallel operation of transformers from the root, adapting to the needs of various large, medium, and small transformer ratio tests, is currently the most advanced technology in domestic ratio testing, with complete testing items and comprehensive measurement parameters.
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 data storage, which can save on-site verification data and has multiple expandable storage options1000The on-site verification results can be provided with 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.

Product features

1True three-phase testing: single-phase power input, internal digital synthesis of three-phase standard sine wave signal source, and high-power amplifier to achieve three-phase power output,0.1%Low distortion, high stability, phase symmetry, better equivalence of test results, and no occurrence of group misjudgment or other phenomena.
2It can perform single-phase measurement and automatic testing of three-phase windings. Both single-phase and three-phase windings can measure polarity and phase angle, completing the measurement in one goABTheBCTheCAThe variable ratio value, error, tap position, tap value and other parameters of the three phases can be automatically identified as group numbers.
3Easy to operate: No need to select wiring method, no need to select wiring group, measurementY/△, △/YTransformers do not require external short circuits and can automatically switch wiring modes based on the selected testing content.
4Tap 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.
5The built-in rechargeable battery can be used as a working power source, so there is no need to search for a working power source on site. (Optional function)
6The concept of measuring phase angle is introduced in variable ratio measurement, which can measure the phase angle at any angle between the high voltage side and the low voltage side.
7Can conduct parallel operation testing of main transformers, truly achieving the detection of transformer parallel operation parameters.
8Good anti vibration performance: The use of connectors enhances the anti vibration performance.
9Adopting7The high-definition color screen displays data and vector graphics with intuitive and delicate effects.
10Revolutionary 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.
11The test source used in this instrument is a standard sine digital source synthesized digitally, with low distortion and not affected by the working power supply.
12Convenient to carry: small size and light weight.
