Types of Lightning Arresters - Circuit Globe

When the high voltage occurs on the line, the gap sparks and the fault current passes to the earth. Hence the equipment is protected from damage. The difficulty with the rod arrester is that once the spark having taken place it may continue for some time even at low voltages. To avoid it a current limiting reactor in series with the rod is used.
