Abstract
This paper analyzes the propagation characteristics of lightning surge according to the type of branch line in distribution system. The types of branch line considered are H-type and PI-type. At each type, the length of main feeder is same, while the number and length of branch line are different. The distribution line is modeled and the various lightning locations are simulated by Electromagnetic Transient Program(EMTP). For each lightning, the various measuring points are selected. Based on the simulation results, the propagation characteristics of lightning surge at each measuring point are analyzed. The analyzed results are verified by travelling wave theory.
