With the development of aircraft technology, electronic equipment has been widely used in aircraft avionics systems, becoming an important part of aircraft power control and parameter acquisition. Aircraft in the operation process will inevitably encounter lightning weather, due to the lightning energy is huge, the electromagnetic interference generated will threaten the normal work of the airborne electronic equipment. Therefore, lightning protection has become an important factor that must be considered in the design process of airborne electronic equipment. With the large number of applications of information technology, the electronic equipment installed in the aircraft is becoming more and more complicated, the degree of integration is getting higher and higher, the application of electronic components is also increasing, the interaction between the airborne equipment cable is getting bigger and bigger, which directly leads to the airborne equipment is increasingly sensitive to lightning, the aircraft is more susceptible to the impact of lightning indirect effects. Thus, indirect lightning protection has become a major consideration in the design process.
