what is a lightning arrester???

Answer Posted / manish kumar meena

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.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
