Surge protection for high-power charging

Charging infrastructure must function reliably. However, functionality is threatened by lightning and surges. Damage to the infrastructure can be caused by direct lightning strikes, indirect lightning strikes or, for example, earth faults and short circuits in the power grid. Based on the lightning protection zone concept, the correct lightning current and surge arresters are used, both for power and data lines. With an integrated protection concept, people and the charging park are protected in equal measure.
