The lightning protection standard is an IEC standard and has therefore been incorporated in the standards of the CENE-LEC* member states whilst taking national circumstances into account. Country-specific standard designations and the associated national calculation values can be selected and displayed in the DEHN Risk Tool software.
To ensure a technically correct external lightning protection system, the protected volume must be properly dimen-sioned according to the height of the air-termination rod. With the DEHN Earthing Tool one can calculate the length of earth electrodes in compliance with IEC 62305-3.
The results of the risk analysis can be printed as a summary or detailed report in the rele-vant language. Specific protection measures must be taken to prevent lightning damage. Knowledge evolved from lightning re-search has also led to improvements in the calculation of the separation distance.
Knowledge evolved from lightning re-search has also led to improvements in the calculation of the separation distance. The current IEC 62305-3 standard requires that roof-mounted structures be located within the protected zone using air-termination rods or elevated air-termination systems (elevated ring conductor or spanned cables).
