Down Conductor

Role of Down Conductors in Lightning Protection

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 …

SS Earth Rods

Importance of Stainless Steel Earth Rods

Scope: Earth rods constructed of austenitic stainless steel according to British specifications. Stainless steel rods are comparable to copper rods; however, they are more anodic than copper and can be used when galvanic corrosion is a concern. The current carrying capacity of stainless-steel rods is lesser as compared to copper. …

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 …

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 …

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 …

What is Substation Earthing? [Explained with Calculations]

The fundamental role of any substation earthing is to dissipate the short circuit current into the earth without drying out the area and to limit the potential gradient throughout the substation to maintain the step and touch voltages within safe values. There are two features considered during the design of …
