5.Why lighting arresters are used in transmission lines?

Question

Accepted Answer

Lightning arresters are used in transmission lines to protect the equipment and infrastructure from damage caused by lightning strikes.

Lightning arresters divert the high voltage surge caused by lightning strikes to the ground, preventing it from damaging the transmission lines.
They provide a low-resistance path for the lightning current to flow, reducing the risk of electrical breakdown and flashovers.
Lightning arresters help in maintaining the insulation levels of the transmission lines and protecting the connected electrical equipment.
They are particularly important in areas prone to frequent lightning activity.
Examples of lightning arresters used in transmission lines include metal oxide varistors (MOVs) and gap-type arresters.
