Surge Protection of Railway System (Traction system)

• There is a wide expansion of the track electrification worldwide.
• We often forget the hidden enemy and widespread damage that comes with overvoltage power surges.
• The easiest ways to understand are those which are derived from the lightning strikes as they can be seen.
• In general, in a typical storm more than 10000 strikes will not be visible but each can contain enough voltage to cause damage to sensitive equipment’s.
• Normally, working faults more regularly such as in motors, generators, due to electronic switching equipments, etc.
• The maintenance and service people should manage all the maintenance, communication, safety and security of the systems.
• Therefore, it becomes very necessary to protect this system.
• Safety measures and careful attention needs to given for each and every part of the system to be protected, Some of the lightning arresters are discussed below.

B) Switching Surges due to External and Internal factors.
