A calculation based on current standards
With the LPS Managerapplication, you quickly obtain a recommendation on the level of protection to apply to a building, a structure, and more broadly, to an entire site. The calculation of the protection level in LPS Manager is based on the standards in force under the document FD C 17-108:2017 (or simplified IEC 62305 standard).
Source AFNOR (FD C 17-108 – January 18, 2017):
"The FD C 17-108 document is based on the IEC 62305-2 standard, from December 2012.
The method is said to be simplified in the sense that it includes only a limited number of parameters compared to the so-called complete method of the IEC 62305-2 standard, of December 2012.
In fact, it only applies to structures:
– for which the fire risk is low or ordinary;
– for which the risk of fire is high but the risk of panic is low;
– which do not contain any explosive product or atmosphere;
– which pose no danger to the environment
Lightning Protection Level (NPF)
A number related to a set of lightning current parameter values that indicates the probability that the associated maximum and minimum design values will not be exceeded when lightning occurs naturally. NOTE: The Npf is used to design protection measures based on the appropriate set of lightning current parameters. The protection level can be defined as I to IV. (IEC 62305 definition) Level I is the highest level of protection.
90% of cases handled by LPS Manager
The use of LPS Manager is suitable for a large number of lightning protection system cases, however in the context of a calculation for a complex structure or one not meeting the criteria of FD C 17-108:2017, we advise you to contact your design office.
100% of files in LPS Manager
If the protection level calculation cannot be performed using LPS Manager, you can enter it directly into the application after performing the calculation yourself according to the complete method of the IEC 62305 standard. If you are unable to do this yourself, we advise you to contact a specialized engineering firm. Gathering and sharing the information within LPS Manager will be essential for the proper processing of your application.
