MEHB-PL transformer calibration device product use
The MEHB-PL transformer calibration device is to verify the technical performance of voltage transformers and current transformers used in the field or in the laboratory. In order to achieve this purpose, the transformer calibrator must form a complete set of transformer calibration device with related equipment. Because there is a close technical relationship between the performance index of the transformer calibrator and the related equipment, in order to correctly study and understand the overall concept of the transformer calibrator, it is necessary to have a basic understanding of the transformer calibration device.
China's transformer calibrator can be roughly divided into three generations: the first generation of electrical calibrators, which are cumbersome to use and complicated to wiring; The second-generation calibrator uses more advanced electronic circuits, which is more convenient to use than the previous generation calibrator, but it needs to manually switch the range gear during the measurement process, and the display information is less during the test. Most of the third-generation calibrators use single-chip microcomputer, so that the intelligence of the instrument has been improved, and some instruments have computer communication interfaces, which improves the level of office automation.
I have an appointment with the author MEHB-PL transformer calibration device product features The single-chip microcomputer is used to realize the functions of measurement, control, display and so on;
There is a computer interface, improve the level of office automation, reduce the intensity of manual labor;
Enough to have a large screen display, provide a friendly operation interface, and rich measurement information;
It can automatically realize transformer measurement, and can automatically switch current and voltage load boxes;
Have good catch-up measures and be able to inform users of misinformation in a timely manner;
The instrument is capable of reaching class 2. At present, most of the calibrators on the market use the resistance-capacitance phase shift 90° method to achieve data measurement, which is easily affected by the ambient temperature and power supply frequency, and once the above environment changes, its measurement data will be more affected.
Because the product will be upgraded and changed, please refer to the parameters of Wuhan Moen official website!
