TAKO since 1979: Safeguarding Structures with Lightning Arrester and Earthing System Solutions

Introduction

Building safety and infrastructure stakeholders prioritise protecting structures from the devastating impact of lightning strikes. This is where lightning arrester and earthing systems come into play, providing an important line of defence in comprehensive lightning protection methods.

This blog post delves deep into the area of lightning protection, examining the critical functions of lightning arresters and earthing systems, as well as how TAKO, a leading name in the sector since 1979, can be your reliable partner in protecting your projects.

Understanding Lightning Arrester and Earthing System

Lightning, a massive flash of electrical energy thrown from the environment, is a serious threat to buildings and their people. To fully protect against this strong energy, a complete lightning protection system is required. This system is based on two major components: lightning arresters and earthing systems.

Lightning Arresters

Lightning Arresters

Lightning arresters are the initial responders in a lightning strike scenario. They are strategically placed on exposed areas of a structure, such as rooftops or antenna masts. Here is a breakdown of their function.

Interception: When a lightning strike approaches, the arrester serves as a preferred channel for the current due to its reduced impedance in comparison to the surrounding structure.

Diversion: Once the current is collected, the arrester directs it away from the building’s electrical system and sensitive components.

Limitation: The arrester reduces the surge voltage caused by the lightning hit, further limiting potential harm to electrical equipment within the structure.

Earthing Systems

Earthing Systems

The redirected electricity from the lightning arrester requires a safe channel to disperse harmlessly. This is where the earthing mechanism comes into action. It is made up of a network of conductors and electrodes that create a low-resistance conduit for current to pass to ground. Let’s take a deeper look at its components:

Earthing Conductors: These normally consist of copper or galvanised steel and link the lightning arrester to the earthing electrodes. They maintain an efficient current flow.

Earthing Electrodes: These are buried underground and create a low-resistance connection to the earth. They are available in a variety of shapes, including rod electrodes, strip electrodes, and buried earth rings, depending on soil conditions and earthing resistance requirements.

The Evolution of Lightning Protection Systems

The history of lightning protection dates back centuries, with Benjamin Franklin’s development of the lightning rod being a watershed milestone. Modern innovations, however, have resulted in major improvements. Industry regulations have tightened, and technology such as Active Early Streamer Emission (ESE) lightning arresters offer increased protective zones. Since its establishment in 1979, TAKO has been at the forefront of these breakthroughs, with over 36 approved inventions that contribute to the ongoing enhancement of lightning protection products

FAQs

Can an earthing and lighting arrester be connected together?

In fact, connecting an earthing system and a lightning arrester is required for a functioning lightning protection system.
The lightning arrester intercepts the lightning strike and redirects the electricity.
The earthing system creates a low-resistance conduit for the redirected current to dissipate harmlessly into the ground.
Imagine the lightning arrester as a conductor and the earthing system as a drain. They cooperate to securely remove the undesirable current.

What is earthing and lightning protection system?

An earthing and lightning protection system, often known as a lightning protection system (LPS), is a set of components intended to protect structures and their occupants from the damaging effects of lightning strikes. It consists of two main parts:
Lightning rods and air terminal wires are examples of components that make up the Air Terminal System (ATS). The lightning arrester is frequently integrated into the ATS.
Earthing System: This network of conductors and electrodes offers a low-resistance conduit for lightning current to safely reach the earth.

Does a lightning arrester need to be grounded?

Yes, a lightning arrester must be grounded.  As previously stated, the arrester diverts the current but does not eliminate it. The earthing system is essential for the final phase, as it provides a safe channel for the current to dissipate. Without sufficient grounding, the misdirected current may go in unexpected directions, causing damage to the structure or electrical systems.

Does earthing stop lightning?

Earthing alone does not prevent lightning. Lightning is a powerful-natural phenomena, and a direct impact cannot be avoided. However, a correctly constructed earthing and lightning protection system, which combines air terminals and earthing, provides a regulated path for the current to safely discharge. This considerably minimises the likelihood of lightning-related harm.

What happens when a lightning rod is not earthed?

If a lightning rod is not correctly earthed, it might create a hazardous condition. Here’s why.
 
The lightning rod will continue to attract strikes.
Without a low-resistance path to the earth, the current can take unpredictable paths.
This can result in arcing, sparking, and potentially damaging the structure, electrical systems, or even injuring persons nearby.
A grounded lightning arrester within the air terminal system directs the current in a safe and specified path, reducing these concerns.
