Need of increased attention
- Old Indian standard ( 1989 – 2015) for lightning protection
was not very comprehensive and hence rarely customers
were serious about good lightning protection system (LPS) .
- New Indian Standard ( since Aug 2015) is very comprehensive
and hence Indian industries need up-gradation in order to
comply with new Indian standard.
- Up-gradation for existing plants / Compliance with new
standard for new plants - - both needs additional engineering
measures and financial investments.
- As per the new Standard, up to 99% risk can be mitigated by
installation and maintenance of LEVEL-1 LPS.
