Specifying lightning, earthing and surge protection is a standards exercise before it is a purchasing one. This is where LPES publishes the working material behind that: how the standards are applied in practice, what the calculations actually require, and where a design choice involves a trade-off worth knowing about.
Technical blog
Over a hundred articles by the LPES engineering team on design method and site practice — the rolling sphere and mesh methods, separation distance, lightning protection zones, soil resistivity testing, natural down conductors, and protection for hazardous areas, open yard equipment and flammable storage. Read the technical blog.
Standards in practice
Each protection pillar carries the standards that govern it, explained on its own page rather than left as a citation list. Start with IEC 62305 and IEC 62561 for lightning protection, IS 3043 and IEC 62561-2 for earthing, IEC 61643 for surge protection devices, or IEEE 1584, IEEE 519 and IEEE 80 for the power protection studies. A full standards library, with a clause-level guide to IS 3043, is being published through this section.
What to read for a given question
| If you are deciding | Start here |
|---|---|
| Whether a structure needs an LPS at all, and at what level | Lightning Protection Systems — risk assessment to IEC 62305-2 |
| Electrode type and size for a given soil | Earthing & Grounding Systems — IS 3043 sizing |
| Which SPD type belongs at which board | Surge Protection Devices — IEC 61643 classification |
| Arc flash boundaries, harmonics or step and touch potential | Power Protection Studies |
| How to write the line items into a tender | BOQ & tender support |
Common questions
Is the technical content specific to India?
Both. The Indian standards that govern day-to-day specification here — principally IS 3043 — are covered alongside the IEC and IEEE standards that the same designs are exported under, because LPES supplies into GCC and African projects on the same certification set.
Can an LPES engineer review a design we have already drawn?
Yes. Send the drawings and the site details through a site assessment request and the review comes back against the relevant clause, not as a sales response.
Do you publish anything that argues against your own products?
Where a design choice has a genuine trade-off — isolated versus non-isolated systems, ESE versus Franklin rods, chemical versus plate earthing in a given soil — the articles say so. A specification built on a one-sided claim fails at commissioning, which helps nobody.
Ask the engineering team a question if what you need is not here yet.
