Lightning arrester is a protective device which conduct
high voltages surges on the power system to the ground.It
consists of spark gap which is connected in series with the
non-variable resistance,its connection is that one end is
connected to the terminal of the equipment which is to be
protected and other end is effectively grounded.
The property of non-variable resistance is that it offers
low resistance when voltage is high.
