Earth Mats

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 …

Step & Touch Potential

What are Touch and Step Potential Requirements?

To grasp the concept of step and touch potential as per IEC 62305-3 (EN 62305-3) How energy dissipates over conductive objects. Some good conductors exist that provide a path to the ground during broken pole or downed wire conditions, such as metal fences, damp soil, and puddles. Other conductors, such …

Essentials of Neutral Grounding System

Objective: Indian Standard IS: 3043 – 2018 [Code of Practice for Earthing – Second Revision] says the following: Earthing refers to the complications which arise when electricity conducts via the ground. The terms earth and earthing here are used whether (or not) the earth is employed as a low impedance …

Earth resistance

What is Earth Resistance? How to measure it?

Electrical systems can fault at any time due to equipment failure, power surges caused by lightning strikes, or variations in the power grid. These faults can be hazardous for individuals handling electrical equipment, as they become an instantaneous pathway for current to flow. It’s here that the concept of proper …

Earthing for a Distribution or Transmission Line

Earthing is an important part of electrical distribution lines. Installation of a protective grounding on the power line structure creates a safe work zone. It neutralises leakages or short-circuit current and offers a simple and easy path for the current to the earth with zero damage potential. Importance of Earthing …

What is the difference between Bonding, Grounding and Earthing?

Follow us on LinkedIn for the latest updates  The importance of Bonding, Grounding and Earthing in electrical systems cannot be overstated. In a factory, in order for the equipment to function properly, the grounded circuits need an effective return path from the equipment to the power source. In any kind …
