The main differences between a lightning arrester and a surge arrester are time and position. In the past, there were only lightning arresters, since lightning was the only place where big power surges would come from. Now, a lighting arrester typically prevents surges from outside the electrical grid, and a surge arrester prevents ones from inside.
"Both are doing the same job,but both are not same".
A surge arrester is device that intercepts electrical surges and sends the spike to ground before it can hurt a connected device. These arresters are also known as surge protectors or lightning arresters, but there are some very small differences between these devices. In most cases, when a surge arrester intercepts a power surge, it fuses itself to prevent transmission. This will stop the surge, but it also destroys the surge arrester. If the arrester is improperly installed, this fusion can cause more problems than the initial surge.
