The primary purpose of an external LPS is to intercept direct lightning strikes, conduct the current safely to the earth, and disperse it into the ground. It consists of three main parts. 1. Air-Termination System

An LPS typically consists of the following components:

Understanding IEC 62305-3: The Standard for Physical Damage to Structures and Life Hazard iec 62305-3 pdf

IEC 62305-3 provides guidelines for the installation and testing of LPS:

A key concept defined in IEC 62305-3 is the external Lightning Protection System, which is designed to safely intercept a lightning flash, conduct its current to the ground, and disperse it harmlessly. An external LPS consists of three primary components: The primary purpose of an external LPS is

While IEC 62305-4 covers SPDs in detail for electronics, Part 3 requires the installation of SPDs at the entrance of power and signal lines to prevent physical damage and fire caused by lightning currents entering the building via service lines.

Electrical and telecommunication lines must be bonded via . While IEC 62305-3 dictates the placement of bonding bars, the detailed selection of SPDs falls under IEC 62305-4 . Separation Distance ( Air-Termination System An LPS typically consists of the

A lightning protection system is continuously exposed to weather and corrosion. IEC 62305-3 emphasizes that an LPS must be inspected periodically to ensure compliance.

The standard provides technical requirements for two primary areas:

Includes electrical continuity and earth resistance testing. LPL I & II: Every 2 years. LPL III & IV: Every 4 years.
