The standard, titled "Protection against lightning – Part 3: Physical damage to structures and life hazard," is the definitive international guideline for designing and installing Lightning Protection Systems (LPS). The latest edition, IEC 62305-3:2024 , was released in September 2024, replacing the 2010 version with critical updates on component selection and protective measures. Core Objective of IEC 62305-3
Protecting human beings from injury due to touch and step voltages in the immediate vicinity of an LPS. Key Components of a Lightning Protection System (LPS)
Preventing physical damage to buildings and structures through a properly designed LPS.
This system prevents dangerous sparking within the structure. Key measures include: IEC 62305-3:2024
According to the standard, an effective LPS is divided into external and internal systems.
This part of the standard focuses on two primary areas of safety:
Intercepts lightning using rods (Franklin rods), meshed conductors, or catenary wires.
The external system is designed to intercept direct lightning strikes and conduct the energy safely to the ground. It consists of:
Provides a direct path for the lightning current from the air-terminals to the earth.
Safely dissipates the lightning current into the ground. 2. Internal Lightning Protection System
