How to install lightning arrester on building?
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 …
What is a Surge Protection Device?
Surge protection devices play a vital role in voltage fluctuations or variations. These fluctuations are the most common behaviours observed in any electrical system. Voltage change can vary from small voltage fluctuations for a short duration to a complete blackout for an extended period. When the voltage drops below the …
Smart Meters in India ─ Types & Application
Smart meters record information on electrical energy consumption, voltage levels, current and power factors. They offer greater clarity on this information to the electrical service providers regarding electrical consumption, help with monitoring the system, and billing. They use advanced metering infrastructure (AMI) that differs from automatic meter reading (AMR.). They …
Cable Glands ─ Need for Electrical Equipment and Switchgears
Cable Gland is the ‘mechanical cable entry device’ attached to the end of electrical cables and secures them to any piece of equipment. They are also commonly known as cable connectors, cable fittings, cord grips, or cable strain reliefs. Cable Glands are vital for terminating cables in harsh or hazardous …
Installation of Cable Lugs
Cable lugs are electrical components used to safely connect wires and cable terminals to electrical equipment or terminate them. They are designed to easily and securely connect and disconnect electrical joints permanently or for maintenance. There are different types of cable lugs available for various electrical applications. They are essential …
Earth Rods – Functions and Advantages
Earth Rods have various functions & advantages. They are also known as electrodes or grounding rods and, their fittings are used for effective earthing systems in overhead and underground electricity distribution and transmission networks. These are used singularly or in groups to: – Form a ground field. – Create a …
Distribution Boxes: Types and Functions
The distribution box serves as the load centre and distributor of electrical power. A distribution box ensures that electrical supply is distributed in the building, also known as a distribution board, panel board, breaker panel, or electric panel. It is the central electrical supply system of any building or property. …
Bimetallic Lugs & Solution for Solar Industry
The solar industry is one of the most flourishing sectors in India. Electricity production using solar energy is getting much cheaper and easy. The bimetallic solutions like bimetallic lugs & joints are playing a crucial role here. In this article, we will discuss how bimetallic solutions are becoming the norm …
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 …
