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 ...
Scope of Electrical Lugs A cable lug also known as a cable terminal is a component of an electrical device that connects the cable to the device terminals. It simplifies the assembly of personnel, maintenance, and repair processes. A cable lug or connector is used when a permanent connection 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 ...
What is a Single Line Diagram? A single line diagram also called the one-line diagram is a symbolic or graphical representation of a three-phase power system. It has a diagrammatic representation of all the equipment and connections. Standardized schematic symbols represent electrical elements such as circuit breakers, transformers, bus bars, ...
Earth resistance refers to the resistance an earth electrode offers to the current flowing into the ground. Ideally, this resistance should be zero to allow fault current to flow quickly into the earth. However, achieving zero resistance is practically impossible. The earth resistance value is different in different locations. Earthing ...
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 ...
Choosing the right Cable Gland shouldn’t be a puzzle. Here’s a shortcut for you. Do you ever wonder how cables safely enter and exit electrical enclosures? A small but crucial component, the Cable Gland makes this possible. In this blog, we will discuss how to select Cable Glands from size ...
Do you know what helps maintain the safety of you and your electrical appliances from fault current? A metal rod called Earth Rod. These Copper Rods establish quality earthing systems in overhead, underground electricity distribution and transmission networks. They provide ground contact in all soil conditions like high voltage substations, ...
A grounding system is a network of conductors that provides a low-impedance path for electrical fault currents to flow safely to the earth. The purpose of a grounding system is to protect people and equipment from electrical hazards, such as electrical shock and equipment damage. In an electrical distribution system, ...
In the realm of electrical grounding, one method stands out due to its unique approach and historical significance: Ufer Grounding. Officially recognized as a concrete-encased grounding electrode in the National Electrical Code (NEC), this grounding technique has proven to be a reliable solution, particularly in arid regions where conventional grounding ...
