Lightning Protection Systems
Lightning Protection Systems (LPS) based on IS requirements
Protecting a building against the direct and indirect effects of lightning is important for the safety of people and equipment in the building.Rather it is a mandatory requirement in several countries for industrial/commercial and multi-storeyed residential buildings.Direct lightning in an installation can create fire and explosion as well as cause severe damages to contents of the building.The new Indian standard IS/IEC 62305 part 1 to 4 published 2015 is based on the international standard IEC 62305 and is a comprehensive standard for protecting building against lightning and its effects.

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.

Foundation Earthing, Ring Earthing, Structural Earthing and Earth Mat
Building with electronic installations need either foundation earth or ring earth for the reliable operation of the installation as strongly recommended in IEC 62305-3.Such an earthing system provides equipotentialisation and hence the effects of transients are reduced.The belief of concrete encased foundation earth is often viewed with suspicion, due to the myth that "concrete is an insulator".Concrete used for the foundations of buildings has certain conductivity and generally a large contact area with the soil.

CPRI has conducted a Two day Work Shop on "Lightning Protection". The two day training program is aimed to create awareness of lightning hazards and offers technical guidance. A large no of participants have attended the workshop. There was a very good response from the delegates. All the lectures were very interactive. We would like to arrange more lectures of the same in the near future.
