"/UploadFile/UserProPic/2015/8/27/20158271657205347400.jpg" alt= "/> to self generating electric welder electromagnetic compatibility problem voltage sag immunity problem research the foundation, developed a high power three-phase voltage self generating electric welder sag resistance Immunity test system. The test system based on MSP430F449 microcontroller as control core, using WEINVIEW MT506 touch screen as man-machine interface, a phase sequence adjustment unit, contactor protection unit, sag generating unit and control unit composed of sags, test methods and parameters through the touch screen can be set, immunity test of single-phase voltage sag and arc welding equipment the three-phase voltage sags of welding equipment according to the national standard, you can also customize the specific parameters of the voltage sag immunity test.
