Experimental and Electromagnetic Field Approach for the Development of Modified Building Protection System

During the lightning activities every air terminal has the equal chances to be hit by the lightning flashes and it produce electric field in the surrounding. Therefore, with the passage of time when the lightning air terminals become aged due to acidic rain and chemical contamination, lightning air terminal (LAT) bypasses on side edges takes place which has not been given much attention by the researchers. A modified lightning protection system (LPS) was proposed in this paper using experimental and electromagnetic field approach. One of the LAT on different geometrical structure was selected as sacrificial point in order to reduce the chances of LAT bypasses. The modified protection system can be referred by different standard to make sure buildings protection. All the experimental work was done using high voltage impulse and ANSYS/MAXWELL was used as a simulation tool. The modified protection technique will help different standards to provide comprehensive protective measures against lightning.
