The need for lightning arresters arises from the potential dangers posed by lightning strikes to
structures, electrical systems, and the safety of people. Lightning is a powerful natural phenomenon
that can cause severe damage, destruction, and even fatalities. Lightning arresters, also known as surge
protectors or lightning rods, are designed to mitigate the risks associated with lightning strikes by
providing a low-resistance path for the lightning current to follow, thus protecting the structure or
equipment from the damaging effects of lightning.
Here are some key reasons why lightning arresters are necessary:
- Protection of Structures: Lightning strikes can cause significant damage to buildings, houses, and
other structures. When a lightning bolt hits a structure, it can result in fire, explosions, structural
damage, or even complete destruction. Lightning arresters help in protecting the structure and
reducing the potential damage caused by lightning.
- Protection of Electrical Systems: Lightning can induce powerful surges or transients in electrical
systems, such as power lines, electrical panels, and sensitive electronic equipment. These surges
can damage or destroy electrical components, disrupt power supply, and lead to costly repairs
- Safety of Occupants: Lightning strikes can pose a significant risk to the safety of individuals
within a structure or in outdoor areas.
- Protection of Equipment and Appliances: Lightning-induced surges can damage or destroy
electronic devices, appliances, and other equipment connected to the electrical system. This is
particularly important in environments where sensitive or expensive equipment is present, such
as industrial facilities, data centers, telecommunications installations, and healthcare facilities.
- Insurance and Risk Mitigation: Lightning strikes and the resulting damage can lead to costly
repairs, replacement of equipment, and potential liability. Insurance providers often require the
installation of lightning arresters as a risk mitigation measure. Having lightning arresters in place
can help lower insurance premiums and provide financial protection against lightning-related
