Earth resistance is the measure of how easily electric current can flow from an electrode into the ground. Lower resistance ensures the current dissipates faster and more safely during a fault. This resistance depends mostly on soil resistivity. To keep the value within safe limits, the soil around the electrode ...
Lightning arrester rods, surge arresters, or lightning conductors are metal rods installed on a building for lightning protection. They protect structures or substations from the travelling waves of lightning and divert the abnormally high voltage to the ground. They are made from copper and brass alloy which are good conductors ...
Follow us on LinkedIn for the latest updates The protective angle method is one of the three routes for lightning protection system design defined by IEC 62305, the international standard for lightning protection design. After the first step of determining the class of lightning protection decided by the Risk Assessment, ...
The electrically conductive connection between the air-termination system and the earth-termination system is the down conductor system. The purpose of down-conductor systems is to safely transport intercepted lightning current to the earth-termination system without causing excessive temperature spikes that could harm the structure. It must be mounted to ensure that ...
What is a Lightning Conductor? A lightning conductor is a thick copper wire or rod fixed onto the tallest point of a building and connected to the ground using a long metallic rod. It protects the building from lightning strikes by providing a low resistance path for the current to ...
Follow us on LinkedIn for regular updates on everything about Lightning Arresters! Well, we all are aware of the lightning strike that occurs during the rainy season. But are we aware of the fact that we need to protect our structure and electrical system from it too? Yes, there is ...
Lightning – a natural phenomenon as breathtaking as it is deadly. It’s a spark that bridges the gap between negatively and positively charged sections of a cloud, and its power can cause significant damage, especially to tall buildings. However, thanks to modern engineering, we have a defence mechanism against this ...
ESE Type Lightning Arrester, also known as Early Streamer Emission Lightning Arrester, protect buildings from direct lightning strikes. The goal of this device is simple. It increases the protection radius compared to conventional arresters, which reduces the number of arresters and down conductors needed for a building, all while ensuring ...
What is Lightning Arrester’s Coverage Area? The Lightning Arrester Coverage Area Calculation (or Air Terminal) is defined as the area within which the arrester effectively protects a structure from lightning strikes. This area depends on the spacing between air terminals. In this blog, we will explain how to calculate the ...
These clamps look small but selecting the wrong one can compromise the electrical safety of your structure. In this blog, you will learn about clamps used in earthing and lightning protection systems. By the end, you will clearly understand the different types of clamps and their applications. At Axis, we ...
