ESE Lightning Arrester Coverage Area - Calculation Explained 📐

In today's video, we delve deep into ESE Coverage Area Calculation for Lightning Arrester systems. This video is a must-watch for Electrical Distributors, Contractors, and Utilities who are keen on understanding:

1️⃣ What is an ESE Lightning Arrester?
2️⃣ What is a Lightning Arrester’s Coverage Area?
3️⃣ How to calculate the Coverage Area?

In this video, we will explain how the Radius of protection is calculated with the formula and with the help of our table!

🌩️ What is an ESE Lightning Arrester?
Also known as Early Streamer Emission Lightning Arrester, this technology is designed to protect structures from direct lightning strikes. It enhances the Radius of Protection, thereby reducing the number of Lightning Arresters and Down Conductors required for comprehensive protection.
Yet, it provides complete protection. It protects by ensuring that the lightning bolts are safely channelled. Instead of striking random objects, the lightning is directed through the ESE lightning arrester. From there, the high-voltage surges are dissipated into the ground safely.

📐 What is a Lightning Arrester's Coverage Area?
The coverage area is the spatial region within which the arrester can effectively protect a structure from lightning strikes. It is represented as a semicircle with a specific radius of protection (Rp).
