What is the rating of LA used at 25kv side in switching station and Traction sub station?

Question

Accepted Answer

The rating of LA used at 25kv side in switching station and Traction sub station depends on the specific requirements and design of the stations.

The rating of LA (Lightning Arrester) at the 25kv side in switching station and Traction sub station is determined based on the voltage level and the expected lightning surge levels.
The LA rating is typically specified in terms of voltage withstand capability and energy absorption capacity.
The rating of LA may vary depending on the specific equipment and system design requirements.
For example, in a switching station with a 25kv system, the LA rating may be chosen to withstand lightning surges up to 100kA and absorb energy up to 10kJ.
In a traction substation, where higher voltage levels and larger equipment are involved, the LA rating may be higher to handle the increased surge levels.
The LA rating is an important consideration to protect the equipment and ensure the safety of personnel in case of lightning strikes or other electrical surges.
