Abstract :
The method to obtain the step voltage near a lightning current by calculating the near zone horizontal electric field was introduced in the first part of this paper. Then, the relationship between the step voltage and the peak value of the lightning current, the electrical conductivity of ground and the radial distance to the lightning current was investigated. Finally some discussions on the safety zone near a lightning current were made.
