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. …

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 …

Introduction to Chemically Charged Pipe Electrode (CCPE)

Earthing or grounding is a critical aspect of electrical safety in any installation. It helps to prevent electrical hazards by providing a safe path for electrical fault currents to flow away from the system. A chemical earthing electrode is an advanced earthing equipment that offers numerous benefits over traditional stainless …

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 …

Plate Earthing Diagram – Explained

Earthing, also known as grounding, is a fundamental safety measure in electrical systems. It’s a method that connects the neutral points of a system to the earth, providing an alternative path for electrical energy to discharge safely during a fault. This prevents dangerous potential build-ups in exposed conductive materials. A …

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 Substation Earthing? [Explained with Calculations]

The fundamental role of any substation earthing is to dissipate the short circuit current into the earth without drying out the area and to limit the potential gradient throughout the substation to maintain the step and touch voltages within safe values. There are two features considered during the design of …

Lightning Protection

Earthing & Lightning Protection System for Substations

In an electrical substation, Lightning Protection System is important for the smooth operation of electrical networks during lighting strikes. Lightning strikes can cause severe damages due to the surge of extra voltage during a strike that is injected into a transformer. As a result, a strike and switching can cause …
