1.7 Assignment of lightning current parameters to lightning protection levels

The natural phenomenon of lightning is subject to certain probabilities regarding the occurrence of various lightning current parameters. These are of varying importance in terms of protection against lightning strikes. Lightning protection levels I to IV are defined for lightning as a natural disturbance variable and for protection against lightning strikes.
High lightning current parameters significantly determine the stress on the components that are required to construct a permanently effective lightning protection system.
Low lightning current parameters, in particular the low peak values of the lightning current, determine the possible points of strike of a lightning discharge in the context of the electro-geometric model (see chapter 1.5). The lower the peak value of the lightning current, the greater the number of possible points of strike on an object.
For each lightning protection level, a set of
