Motor comprehensive protection setting instrument

Motor comprehensive protection setting instrumentOn the basis of the original thermal relay tester, specialized design is carried out. By adopting power electronic adjustment technology, selecting imported high-power IGBT tubes, and eliminating bulky autotransformers, a new generation of lightweight and portable thermal relay tester has been developed. The portable thermal relay tester reduces weight and volume by 45% compared to traditional devices that use autotransformers, truly achieving lightweight and portability, greatly reducing the workload of on-site workers.

Motor comprehensive protection setting instrumentUsed for the calibration of motor protectors, current type motor protectors, and thermocouples. In fact, based on a large number of experiments, the instrument has proven that it can not only test and verify all current type motor protectors, but also effectively inspect and test all overcurrent automatic protection devices. This instrument adopts advanced microcontroller control technology in its design, making it easy and convenient to operate during use. Throughout the entire testing process, the performance is reliable and stable, and the readings are intuitive and fast. The application of high-precision sensors effectively ensures the accuracy of the test data.
