Electrical earthing calculations are an integral part of electrical protective wiring. There are many pieces of equipment and appliances with metal surfaces around us. These metal surfaces could become energized due to lightning or wiring faults. If they do not have sufficient earthing and a person touches this surface, he …
What is an Earth Electrode? Earth Rods are a type of Earth Electrode. An Earth Electrode is a conducting element buried directly in the ground, facilitating the flow of fault currents towards the ground. This means that Earth Electrodes are metallic and, since they have to be buried for long …
An Electrical Conductor is a material which allows electricity to flow through it. Conductors can generally be classified by the metals they are made from, which depends on what purpose a conductor is used for. In this blog, we will discuss two of the widely used conductors, i.e., Copper-clad steel …
In this trending era of technology and development, earthing in substations plays a vital role. An electrical power system comprises a network of electrical elements that can be used to generate, distribute and transmit electrical energy through transmission lines. A substation is a part of an electrical power system that …
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 …
A multiport insulation piercing connector (IPC) is also referred to as a satellite connector for ABC cable. Multiport connectors are extensively used in urban power distribution systems based on aerial bundled cables (ABC). There are many good reasons for using multiport connectors in different power systems, especially in distribution systems. …
What are Cable Glands? Ever wondered how cables enter and exit electrical enclosures safely? The unsung hero of this process is a small yet significant component: The Cable Gland. Among these, the Single Compression Cable Gland plays a critical role. They not only allow cables to pass through safely, but …
Aerial Bunched Cable (ABC) is an innovative concept for Over Head power distribution. When compared to the conventional bare conductor OH distribution system, ABC provides higher safety and reliability, lower power losses, stability in terms of voltage regulation and ultimate system economy by reducing installation, maintenance and operation costs. This …
What is a Busbar? A busbar is a metallic conductor that serves as a central hub for multiple electrical connections. It can be solid, hollow, or flexible, and comes in various shapes. In this blog, we will understand the Types of Busbars and their roles in respective applications. Essentially, it’s …
