Protection against lightning on monitoring system of transmission line icing

This article introduced the design background of online monitoring system of transmission line icing, and the reason of it being struck by lightning, which is easy to be received in the thunder and lightning environment. The article also proposed a method about the monitoring system of transmission line icing protecting against lightning, and analysis devices of protecting against lightning, over current and over voltage. It provided the design reference of online monitoring system of protection against lightning on the open country transmission line and the towers. © 2011 IEEE.
