In recent years, the research and development of gas discharge theory, material science and electrical measurement technology, which are related to the field of electrostatic discharge (ESD), have gradually moved from the experimental stage to the practical stage. At the same time, people have gradually found that the harm caused by ESD to human beings is very alarming. It can not only affect the normal life of human beings, but also limit the improvement of automation production level. Based on traditional electrostatic discharge the simulator with single equipment and limited function, can not meet the all-round and multi-purpose experimental requirements of electrostatic discharge. To solve this problem, a complete experimental simulator including electrode simulation, azimuth conversion and circuit transmission was designed and implemented. The device is mainly composed of six parts: base, support frame, metal ball, discharge needle, insulating ring and azimuth dial. It can meet the experimental requirements of electromagnetic field in different polarization directions, and also can judge and identify the basic polarization direction of electromagnetic field in different altitudes and positions. The system is innovative and advanced, and provides powerful hardware support for the study of electromagnetic induced electrostatic discharge experiments.
