SN Engineering Lightning Protection LIGHTNING, ' A CAPRICIOUS, RANDOM, AND UNPREDICTABLE PHENOMENON. The purpose of a Lightning Protection System (LPS) is to intercept all lightning strikes entering a building, redirect them to the ground, and distribute them evenly across the ground. In order to prevent dangerous flashover and lightning-caused fires, all metallic installations in the building must be made at equal potential. A LPS is regarded as the most effective measure for protecting the structure and its contents against physical damage or degradation. The goal is to prevent thermal, mechanical, and electrical effects that can cause damage to the protected structure or to humans via touch or step voltages within the structure. With our entire range of Lightning and Surge protection solutions from Risk Assessment, Design, Supply, Installation and Testing as per IS/IEC 62305, you can secure your building and assets from the dangers of lightning.
