ED0202B series of fully automatic transformer integrated characteristics test bench for power transformers of the main electrical properties of the factory testing and assessment tests, simple operation, safe to use, the main items of the factory test.
The use of color display, operation of the whole Chinese prompts, realizing the test of the whole process of real-time monitoring. It sets the test of a wiring display, data acquisition, analysis and processing, measurement and control, storage, printing, protection in one, the whole process of the test is completed automatically, with high efficiency and high precision of the outstanding advantages:
(1) with a backlit LCD display, while displaying the three-phase voltage and current, such as the 18 parameter; digital instrumentation to replace the pointer instrumentation, all the test data are real-time screen (lock) display, avoiding the test process in real-time (lock) display, to avoid the test process. All test data are displayed on the screen in real time (locked), avoiding errors caused by parallax, conversion, calculation and other factors during the test. Make the test more accurate. In particular, it completely solves the difficulties of the operator to read and see many meters and record many sets of data at the same time, and ensures the accuracy and reliability of the test data.
(2) The data processing adopts automatic storage and microcomputer printing mode, the data form is beautiful, standardized, neat handwriting, clear. All the test data are filled into the corresponding form in real time, to avoid manual transcription recording process, to ensure the authenticity and reliability of the data. Users also need to set their own print format.
(3) The test bench is also equipped with the functions of waveform ki calibration, test lead resistance calibration, and transformer error calibration.
(4) The test bench can be made into a desktop, portable, simple, standardized according to the user's needs to facilitate the use of different occasions.
(5) Multi-screen menu operation, easy to operate, automatic calculation of the parameters;
(6) voltage and current ratio can be set, directly display the measured value;
(7) test bench using Access database to save the original data, can be convenient to be tested by the equipment of all the parameters, test data, ambient temperature, the date of the test, etc. information is stored, the formation of equipment files, easy to query and analyze later. Equipment files, easy to query and analyze later.
(8) can measure the power of low power factor range;
(9) strong anti-interference, overload alarm indication, line connection error protection, with over-voltage, over-current protection and other functions.
