Effect of Lightning on the Electrified Transmission Railway System

Professor Avishkar Vijay Wanjari

The continuity of supply in order to fulfil the demand of consumers is of great concern and has become need of an hour. Transient condition due to various possibilities leads to over voltage. This over voltage on various Electrical elements are of great concern and are meant to be studied in depth in order to reduce the chances of power failure and any other faulty conditions. The focus of this paper is to see the effect of lightning on the railway overhead line with typical using DC overhead line, also the effect of lightning on the various appliances which are used to produce DC supply for the Railway line. In order to design the DC overhead system PSCAD/EMTDC software was used for designing and further investigation was done with the help of the said software. The consequences of transient over voltages caused due to lightning condition and the effective method for eliminating such condition with the help of surge arrester is discussed under this paper.
