Atmos Plus characteristics (Atmos Pro and Atmos LE has fewer functions, see below)

Current version:

Version X1.2 (11.2) - latest update:, Sep 2016

Main uses

Risk analysis

LPS design for Electro Geometric Model (EGM) and Faraday cage

Safety distances


IEC 62305:2010 (International)

NFPA 780:2014 and NFPA 780:2017 (USA)

NTC 4552:2008 (Colombia)

NBR 5419:2015 (1) (Brazil)

English (2), Português Brasileiro

Data required:

LPS (air terminals, down conductors and grounding): structure dimensions, natural metallic elements, then several parameters options (see docs)

Risk analysis: division of structure in zones (according to chosen standard), parameters options (see docs); data of Service Lines (length, installation, …)

Locations (structure) Models:

Typical industrial buildings, Tall Buildings (like residential or office building) and Houses

Open areas, parking lots, sport courts

Isolated structures


Materials database for air terminals, cables, rods, connections (weld and compression) and others, fully editable, with dimensions, description, picture, cost, labor time for instalation and labour cost, as well as suppliers database (also editable, of course)

Each LPS component can be turned On or Off to allow the use of natural elements like rebars or a metallic roof or structure

Design Options comparison:

Each Location (a structure or area) can have several Options, Zones and Service lines, then each Option has its own materials choices (for ex. masts of different heights or masts x cage) and a selection of the Zones and the Services connected.

Risk comparison includes risk components (RA, RB, …) and totals (R1, R2…) of each Zone and then totals between Zones; then risk total between Options (see docs).

Atmos also compare material x labor costs, and relative costs of air terminations x down conductors x grounding, so you have all the information needed for a fully-optimized design selection.

Reports generated in PDF

Data-sheet (purchase info) of materials used


Manual - inside software and in PDF format

Tutorials - inside software and in PDF format

E-book: see below

Presentations: the presentation slides of a two-day seminary are available inside the software


Portuguese: full digital edition of our book “Proteção Contra Descargas Atmosféricas” (thousands copies of the print edition sold previously) included inside the program

English: compact edition of the book, with enough theory for efficiently using the software and examples not covered on the Manual or Tutorials (see above)

Other functions:

Verification of the protection offered by a structure with LPS to its surroundings, like a nearby house, a backyard or people on the sideway.

Protection of an open area: parking lot, sporting courts and others (see docs)

Data-sheet for each material (air terminal, rod, cable, connection) with full specification.
