What is Maintenance Free Earthing?
Earthing, also known as grounding, is the practice of transferring electrical charges to the ground through low-resistance cables or rods to quickly discharge any stored energy. There are two main types of earthing: maintenance-free earthing and

Cable Glands Size Chart – Explanation for Gland Selection
Fasteners are hardware components like screws, nuts and bolts that mechanically join two or more objects together. Fasteners are used to create non-permanent joints, that can be dismantled without damaging the joining objects. Unlike fasteners; welding, crimping, soldering are examples of creating permanent joints where the connected objects cannot be …
Fasteners – Types and Features
Fasteners are hardware components like screws, nuts and bolts that mechanically join two or more objects together. Fasteners are used to create non-permanent joints, that can be dismantled without damaging the joining objects. Unlike fasteners; welding, crimping, soldering are examples of creating permanent joints where the connected objects cannot be …
House Earthing – Design & Testing
Earthing connects all the major electrical equipment in our house such as fridge, AC, washing machine, grinder to the ground. So when there is an event of a power surge or lightning strike the extra current formed in the system is easily drawn down to the earth, protecting them from …
Earth Mats – Why do we need them?
An Earth Mat is a mesh formed of bare metallic conductors and buried in shallow soil to provide better safety from touch and step potential. Earth mats are a part of the grounding system implemented in substations, production plants, industrial areas, etc., where high power handling occurs. More efficient grounding …
Pipe Earthing VS Chemical Earthing – Explained with Diagram
Electrical circuits are involved with an adequate amount of energy to cause electric shock hazards in case of a fault. A fault can occur due to power surges, leakages due to faulty equipment, lightning strikes hitting directly or indirectly and so on. So it is necessary to focus on the …
Installation of Lightning Conductor – Step by Step Guide
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 flow to the earth rather …
How are Earthing and Bonding different?
Earthing and bonding are two technical terms we come across when we deal with the safety aspect of an electrical system. We have all heard about earthing that is done for safety purposes during the electrical installation, but do we give much thought when it comes to electrical bonding. Both …
How to Use Exothermic Welding?
Exothermic welding, also known as exothermic bonding, thermite welding (TW), and thermit welding, is a welding technique that permanently joins conductors using molten metal. An exothermic reaction of a thermite composition heats the metal, and no external source of heat or current is required. An aluminothermic reaction between aluminium powder …
Role of Down Conductors in Lightning Protection
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 …
