HAZARDS AROUND

While working live in the energized grid, presence of voltage around the workers requires special attention. However, live-line (live working) techniques are widely applied for decades, several accidents in the past prove that the level of safety must be improved to minimize the number and seriousness of injuries in the future.
In the high voltage grid, bare-hand method is a common technique for safe live work. In the surroundings of any energized equipment,...

Advancements in Lightning Rod Design: Early Streamer Emission (ESE) Technology

Lightning protection systems have evolved significantly, with Early Streamer Emission (ESE) technology emerging as a groundbreaking advancement in lightning rod design. ESE technology aims to proactively protect structures from lightning strikes by initiating an upward streamer earlier than traditional lightning rods. This article delves into the concept of ESE technology, its potential benefits, limitations, and its impact on modern lightning protection strategies.

Understanding Early Streamer Emission Technology

ESE lightning rods are designed to preemptively react to the electrostatic conditions that precede a lightning strike, creating an upward leader streamer ahead of natural conditions. This proactive approach increases the probability of capturing the lightning discharge directly, thereby enhancing the protected area's safety.

Mechanism of Action

ESE devices work by detecting the rise in ambient electric field strength as a thunderstorm approaches. Once a certain threshold is reached, the device emits a streamer earlier than...
