This paper discusses about lightning protection system for distribution line system. It contains lightning data analysis, evaluation of existing condition and the improvement of lightning protection system. The recorded data shows that the distribution line often experiences disturbances and damage such as broken transformers, broken arresters, line shutdowns etc. Lightning has the greatest potential as a cause of faults that occur in distribution line. By the research and calculation, some design of protection system had been proposed. In order to improve the performance of distribution line, the improvement of Ground Shield Wire, Metal Oxide Arrester and Grounding System must be done. Then, Multi Chamber Arrester is new technology which is also used to protect the distribution lines from the overvoltage of lightning. Several installations carried out in the field are also presented in this paper.
