Design and Performance Analysis: Lightning Protection-Marking of Air Terminals and Down Conductor-Perspective of Bangladesh

Abstract

This project focused on installing of lightning protection system and its equipment’s. This project was implanted for both shade building and full building with a rooftop. The objective of replacing air-terminal is to catch the strike of lightning and conveyed the current through the down conductor to earth pit. The whole process was followed by BNBC-2006 to make sure a structure or building safe from lightning. As it is essential for factories and industries to take protective action to make ensure the industrial electrical equipment’s, as well as the life of the workers, do work there. To monitor the working process, the Lightning counter device was used to detect how many strikes it caught. The risk assessment of lightning protection system has been done considering 7 index factor (A, B, C, D, E, F, and G), which recommended LPS is essential by calculating total index figure. The diameter of air-terminal was selected as 8 mm and air terminal height was varied 500 mm, 700 mm, 800 mm, 2 meters and 2.5 meters. Therefore, adopting the meshing technology following the BNBC-2006 can be the challenging and easily adaptable for the perspective of Bangladesh.
