Abstract

Considering the complexity of the geographical surroundings and the height of 10 kV distribution line, the impact of trees on the lightning performance can not be ignored. A model of lightning position judgment and overvoltage calculation based on the concept of striking distance is built. With the theory of orthogonal test, the main factors of trees' influence on lightning performance are figured out. The results indicate that the location of trees is the main factor. In practical engineering, suitable management of vegetation can improve the lightning performance and reduce the lightning failure of 10 kV distribution line.
