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
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) iec 62305-3 pdf
This part of the standard focuses on two primary areas of safety:
According to the standard, an effective LPS is divided into external and internal systems. Provides a direct path for the lightning current
Preventing physical damage to buildings and structures through a properly designed LPS.
Intercepts lightning using rods (Franklin rods), meshed conductors, or catenary wires. Intercepts lightning using rods (Franklin rods)
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
The external system is designed to intercept direct lightning strikes and conduct the energy safely to the ground. It consists of:
