EMC compatible buildings for installation of Electronic Equipment.

The protecting electronic equipment in buildings against Electro Magnetic Pulses (EMP) has become important due to the increased use of sensitive electronic systems.
Improvement of construction techniques plays a major role in increasing the efficiency of a building against EMP, which is unfortunately not followed in most of the buildings due to the lack of awareness. An EMP is a short burst of electro magnetic energy. Such a pulse may occur in the form of a radiated field or a conducted electric current depending on the source and may be natural or man-made.EMP has become a known subject nowadays due to science fiction movies and is also one of the widely researched subject where modern military weapons with EMP emissions are developed that can destroy electronic systems in specific places.Lightning is the largest natural EMP whose effects can destroy electronic equipment in a large area.This is due to the induced transient voltage in long wires created due to the magnetic field of lightning.Various studies proved that effects of Lightning Electro Magnetic Pulses (LEMP) can be felt as far up to 2 km radius from the point of lightning strike.Modern electronic equipment are sensitive to Electrical and Electromagnetic disturbances in the installed environment.Reducing the effects of LEMP by the way of shielding and bonding will protect this equipment.Techniques adopted nowadays in most of the high raise buildings do not meet the requirement of LEMP protection measures, but invite additional problem.LPCI’s effective protective measures should start from the foundation to ensure that the building’s steel installations are bonded together to create faraday cage protection against EMP.This cost effective measure ensures maximum safety for today’s as well as tomorrow electronic equipment.
