Lightning protection zone conceptThe lightning protection zone concept allows to plan, implement and monitor protection measures, thus ensuring that all relevant devices, installa-tions and systems are reliably protected at reasonable costs. In this context, a building is divided into zones according to the level of threat. Neces-sary protection measures, in particular the lightning and surge protection devices and components, can be defined based on these zones.

A lightning protection zone concept in conformance with EMC (electromagnetic compatibility) regulations includes external lightning protection (air-termination system, down conductor, earthing), equipotential bonding, spatial shielding and surge protection for the power supply and informa-tion technology system. The definition of lightning protection zones can be found in the table.

Surge protective devices are sub-divided into lightning current arresters, surge arresters and combined arresters according to the requirements on their place of installation. Lightning current and combined arresters, which are installed at the transition from LPZ 0A to 1 or 0A to 2, fulfil the most stringent requirements concerning the discharge capacity. These arresters must be capable of conducting partial lightning currents of 10/350 wave form several times without destruction, thus preventing partial lightning currents from entering the electrical installation of a building.

Surge arresters are used at the transition from LPZ 0B to 1 or downstream of the lightning current arrester at the transition from LPZ 1 to 2 and higher. Their function is to further minimise the residual of upstream protection stages and to limit surges induced or generated in the installation.

The lightning and surge protection measures at the boundaries of the lightning protection zones described above apply to both power supply and information technology systems. Comprehensive implementation of the measures described ensures permanent availability of the system of a mo-dern infrastructure.

Definition of lightning protection zonesLEMP protection measures for structures with electric and electronic systems according to EN 62305-4

▪ LPZ 0A Threat due to direct lightning strikes, impulse currents up to the full lightning current and the full lightning field.

▪ LPZ 0B Protected against direct lightning strikes. Threat due to impulse currents up to partial lightning currents and the full lightning field.

▪ LPZ 1 Impulse currents limited by current sharing and SPDs at the zone boundaries. The lightning field is mostly attenuated by spatial shielding.

▪ LPZ 2 Impulse currents limited by current sharing and SPDs at the zone boundaries. The lightning electromagnetic field is mostly attenuated by spatial shielding.
