4 FAQs about Technical Support for Lightning Protection of Outdoor Energy Storage Cabinets

How do I ensure a technically correct external lightning protection system?

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.

What is a lightning protection standard?

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.

How to protect a pitched roof from lightning?

Protective angle method Rolling sphere method for four air-termination rods on pitched roof surfaces 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.

How has Lightning re-search changed the separation distance of a roof?

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).
