In order to improve the reliability of power supply, a large number of GIS equipment and its intelligent components are used in smart substations. In order to further study the electromagnetic disturbance characteristics of intelligent component ports under lightning, we developed a set of GIS device intelligent components port electromagnetic disturbance measurement system. First, the hardware structure of the GIS device and its intelligent component characteristic measurement system is given, and the corresponding software main program structure is given in this paper. Then combined with the engineering practice, the structure of the corresponding test experiment system is given. Using this experimental test system, the lightning electromagnetic disturbance characteristics of GIS equipment and its intelligent components under different conditions are obtained. The results of this study can be used to study the overall lightning stroke characteristics of intelligent substations.
