The distribution system is formed from number of elements which runs continuously in order
to complete the demand of consumers. Transient over voltages in the power distribution system is
the most important factor which should be considered while developing and designing a new system.
Considering the importance of continuation in supply in order to complete the demand, a proper
protection device should be implemented. So with this importance the said project was started.
Under this paper, the effect of lightning on the railway overhead line is seen along with the
other parts and elements which plays important role in order to run this over head lines.
PSCAD/EMTDC software was used to design an Electrified railway system in order to investigate
the consequences of transient over voltages caused due to lightning phenomenon. This paper also
highlights the effective use of surge arrester in order to protect the system from the surges.
