Lightning Arrester Protection Design

A lightning arrester, also known as a surge arrester or lightning rod, is a device designed to protect electrical and electronic equipment from damage caused by lightning strikes and other electrical surges. The primary purpose of a lightning arrester is to divert the excess voltage and current caused by lightning strikes or transient voltage surges to the ground, thereby preventing it from damaging sensitive equipment connected to the electrical system. Lightning arresters are commonly installed on power lines, telecommunication lines, buildings, and various types of electrical equipment.

 

There are different types of lightning arresters, including:

ESE Lightning Arrester

ESE Lightning Arrester’s objective is to become the point of discharge for the lightning bolt, instead of the bolt hitting a random object such as a solar panel or the side of the building. By becoming the point of discharge, the electricity can be safely conducted into the ground using the entire lightning protection system, protecting the structure or solar park.
As per NFC 17-102, the ΔT for an ESE Lightning arrester should be at least 10μs – this means that the emission time of the ASLA ESE is at least 10μs faster than those from a Franklin Rod. Our range of ASLA ESE products ranges from a ΔT of 10μs to 60μs, depending on the requirements of the project.

Model Radius of Protection (m) Height (mm) Width (mm) Diameter of Rod Maximum (mm)
ASLA 15 58 321 105 20
ASLA 30 71 341 132 20
ASLA 60 89 400 205 25
ASLA 60A 107 400 205 25

 

Conventional Lightning Arrester

Spike Lightning Arrestor is a metal rod, made of copper and, used as part of lightning safety to protect tall or isolated structures (such as the roof of a building or the mast of a vessel) from lightning damage.

What Is The Difference Between Conventional And ESE Lightning Arrester

The ESE lightning arrester can cover a larger radius compared to a Conventional lightning arrester. As per NFC 17-102, the ΔT for an ESE Lightning Arrester should be at least 10μs. At Axis Electrical Components, we have a range of products from the ΔT of 10μs to 60μs

 

Install Lightning Arresters on Building for Ensuring Safety!

The primary reason to install lightning arresters on buildings is to protect them from the hazardous impacts of lightning. Lightning arresters or rods intercept this voltage and provide a safe path for the lightning current into the ground. While it does not decrease the likelihood of a building being struck by lightning, it gives a direct trail to the ground, preventing the structure from fire, explosion, and electrical surges resulting from lightning strikes. Lightning preferentially strikes the arrester instead of passing through the structure where it could start a fire or cause electrocution. The arrester conducts the current to the ground through a wire. Lightning rods are also called finials, air terminals, or strike termination devices. The arresters are designed and developed following UL (Underwriter Laboratories) standards. While choosing lightning arresters, these standards must be verified.

Installation

The arresters’ installations are as per the international standards as followed in a region or country.
Lightning arresters are part of the external lightning protection installation and are installed on the roof of the building to intercept any lightning before it strikes the structure. IEC 62305 PART 1 to 4 has defined guidelines for lightning protection conductors and lightning rods.

As a single component of lightning protection, lightning arresters require a connection to the earth to ensure protective function. They come in various forms, including hollow, solid, pointed, rounded, flat strips, or bristle brush-like. These rods have one main common attribute, they are all made of conductive materials such as copper and aluminium. Copper and its alloys are the most common materials used in lightning protection

What is a Lightning Strike Counter?

A lightning strike counter is used to record the number of lightning strike events. It gives us the exact number of lightning events experienced by the lightning protection system, thus helping us to identify if the system requires any maintenance. It is attached to the Down Conductor of a lightning protection system and records the data when current passes through it. Water-proof Lightning Strike Counters are also available for Surge Protection Devices, Lightning Rods, etc. Some advanced Lightning Strike Counters are able to identify the amplitude and polarity of the lightning, the date and time of the occurrence etc. apart from the number of lightning events.
