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 ...
What is a Lightning Conductor? 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 ...
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 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 ...
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 ...
Suspension Clamp, Service Clamp, Anchoring Clamp, Tension Clamp & High Tension Clamp are some of the crucial components of the AB Cable System. This blog helps you understand the material used for manufacturing, technical features and advantages of various clamps. Aerial Bundled Cable (ABC) is a new concept for power ...
Distribution Transformers are an important component of the power distribution network. They play a major role in providing an uninterrupted power supply to consumers. They are one of the most reliable components of the power grid, yet there can be situations where they fail. Electrical damages are one of the ...
The latest 2023 edition of NFPA 780 covers traditional lightning protection techniques for a wide range of structures such as ordinary buildings, structures of wind turbines, watercraft, and those with flammable and explosive materials. The purpose of the standard is to safeguard persons and property from hazards arising from exposure ...
What is IP rating? IP rating or IEC 60529 grades the resistance of an enclosure against dust, water or other contaminants. It provides a list of the degree of protection offered by mechanical and electrical casings or enclosures. Electric equipment malfunctions or gets damaged when water or dust enters it. ...
