An external lightning protection system should be installed to protect the building from direct lightning strikes. The air terminal is placed on the rooftop of the building. A down conductor to the air terminal to the earth electrode. When lightning strikes the air terminal, the electricity flows directly to the earth through the lightning conductor. It will bypass the flow of high value of current to other parts of the building.

External Lightning Protection Methods
Lightning Protection Angle Method
The Lightning Protection Angle Method determines the protected area of a building by defining a protective angle from the lightning air terminal. This method helps assess whether roofs, structures and exposed equipment are within the protection zone and supports effective lightning protection system design in accordance with applicable standards.
Lightning Protection Mesh Method uses a network of interconnected conductors installed across the roof to create a protective mesh. It safely intercepts lightning strikes and provides a controlled path for lightning current to flow through down conductors into the earthing system, helping protect buildings, occupants and electrical assets.
Lightning Protection Gantry Wire Method
The Gantry Wire Method is a lightning protection technique that uses elevated overhead conductors supported on gantries to intercept lightning strikes and safely conduct lightning current to a properly designed earthing system. It is suitable for protecting large buildings, industrial facilities, open areas and structures where conventional air terminals may not provide adequate coverage.
Premium-grade lightning arrester air terminals built to intercept direct strikes and deliver a low-impedance path to ground for optimal structure protection.
High-conductivity copper down conductor strips engineered to carry heavy discharge currents safely from air terminals to the earthing network with minimal voltage drop
