Erstwhile IS 2309 was superseded by IS/IEC 62305 which is a comprehensive standard so that, not only structures and people are protected but also the electronics inside the structure. Because of this change, NBC- National Building Code & CEA- Central Electricity Authority regulations were also revised to adopt the recommendations given in IS/IEC 62305. Risk analysis of the building that needs protection is covered in detail, and this being a specialised activity, it has to be carried out by experts who are aware of the developments so that customers have their investment, well protected. Hence, it is mandatory to conduct an audit, collect data for risk assessment and implement the recommendations of risk assessment so that People, structure and all electronics inside the structure are well protected and within the tolerable levels.
METHODOLOGY OF LPS ADEQUACY STUDY:
Ascertain whether lightning protection system is provided for all the structures in the facility & if so provided, to which Indian/international standard they conform to.
If they conform to IS 2309 or NFC 17-102, then they are invalid, as highlighted in NBC 2016 and hence risk analysis to be done as per IS/IEC 62305 and recommendations to be implemented to bring the loss of human life and loss of economics under the tolerable levels.
To reduce the losses due to lightning, protection measures MAY BE required. Whether they are needed & to what extent, should be determined by the Risk Assessment (IS/IEC 62305- 2)
Protection techniques that can be implement includes either standalone techniques or in combination of different techniques:

Lightning protection as per LPL 1 to 4
Co-ordinated SPD protection
Fire protection (manual or automatic)
Soil equi-potentialization/ Earthing
Equi-potential bonding, shielding & routing.
In 1996 JEF was incorporated as Private Limited Company and has since successfully completed many turnkey projects for a number of leading companies in India and also abroad in the field of Lightning Protection & Grounding.
JEF Techno was established in the year 1994. The Company pioneered in providing high-quality solutions including design, installation, testing and commissioning in the field of lightning protection and grounding, which was hitherto had a vacuum in that domain. Over the years, JEF had carved a niche place in the fields of Lightning Protection and Grounding. This ideology continues to be at the core of our business philosophy, even today and JEF continues to be a favoured partner by all stakeholders. In 1996 JEF was incorporated as Private Limited Company and has since successfully completed many turnkey projects for a number of leading companies in India and also abroad in the field of Lightning Protection & Grounding. On the services front, the company provides comprehensive and innovative solutions for electrical safety and EMI/ EMC. Over the last decade, our ‘Technical Services Team’ had developed a foolproof method of detecting open connections in buried grounding systems, which have been widely accepted and appreciated by the Industry.
