ABB Lightning Protection System

Early Streamer Emission (ESE) air terminal advanced lightning protection system. In this system the air terminal triggers the continuous upward leader before any other object within its radius of protection. This feature is referred to in the regulations as the advance time of an ESE air terminal (ΔT). The earlier the upward leader is triggered, the larger is the distance where the downward leader is intercepted, thus protecting a greater area against lightning (standards limit it to ΔT≤60 μs). It is [...]

Lightning Protection System in Bangladesh.

Lightning is one of nature’s most powerful and destructive phenomena. Lightning strike present a real and significant threat to life, to the structures in which we live and work, and to the electronic systems which support us in our daily lives. The consequences of lightning can be devastating. Direct lightning strikes damage structures, and create fire, explosion and electric shock hazards.   Indirect lightning creates transient overvoltage’s which degrade electronic system disrupt essential services. It is significant that indirect lightning can run up [...]

Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth. Even the all-powerful Pointing has no control about the blind texts it is [...]
