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 ...

Pipe Earthing

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 ...

Earthing - Bonding

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 ...

Earth Pit

Earth Pit – Technical Aspects & Construction

An Earth Pit is a type of enclosure used in earthing systems to access and maintain the earth electrodes and other components of the earthing system. It is a type of underground box, typically made of reinforced concrete, that is installed at the site of the earthing system. The Earth ...

Ground Potential Rise

Ground Potential Rise Study

Scope: The result of a ground electrode impedance, referenced to remote earth, and the current that flows through that electrode impedance is known as Ground Potential Rise or Earth Potential Rise (as specified in IEEE Standard 367). The maximum electrical potential that a (substation) grounding grid can achieve relative to ...

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 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 ...

SS Earth Rods

Importance of Stainless Steel Earth Rods

Scope: Earth rods constructed of austenitic stainless steel according to British specifications. Stainless steel rods are comparable to copper rods; however, they are more anodic than copper and can be used when galvanic corrosion is a concern. The current carrying capacity of stainless-steel rods is lesser as compared to copper. ...

TT Earthing Sytem

What is TT Earthing System? Detailed Explanation

Scope   Over the last century, electrical safety standards have evolved into very sophisticated systems that encompass all components of a safe installation, including TT Earthing Systems and other types in the category. In Low-voltage (LV) Electrical Installations, the reference standard IEC 60364 is used to determine the actions to ...

Equipotential Bonding

Equipotential Bonding – Everything You Need To Know!

Introduction Earthed materials connect to the conductive surface of the Earth. They are connected for the safety purpose of routing defective current into the ground (by blowing a fuse) or dissipating potentially hazardous discharges. When numerous earthed items are connected, the magnitude of their voltage is limited, and a harmful ...
