ESE Lightning Arrester

Installation Of An ESE lightning Arrester

A lightning arrester protects the electrical network and the structures from lightning. When lightning strikes, it creates massive destruction and damages the equipment. A lightning arrester or a surge diverter protects the equipment at the substation. The lightning arrester bifurcates the abnormal high voltage to the ground without affecting the ...

What are lightning conductors & how do they work?

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 ...

Importance of Earth Mat in Substation

The earth mats or grounding mats bring the connection to the earth indoors. They usually connect through a conductor inserted within the ground port of an electrical outlet. They help in limiting the ground potential & protect against the faulty current. They are used in a place where the large ...

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 ...

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?

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 ...
