Abstract:
In order to analyze the influences of lightning radiation electromagnetic fields on power equipments accurately,the approximate computational formula of lightning radiation electromagnetic fields for horizontal perfect ground is derived based on the approximate numerical expression of lightning current of Heidler function.The transient electromagnetic scattering properties of high voltage iron towers under lightning radiation electromagnetic fields are analyzed by time domain integral equation(TDIE)method.The results indicate that the induced current amplitude on the surfaces of iron towers mainly depends on the distance between the towers and lightning strike positions,has nothing to do with the azimuths between the towers and lightning strike positions.
