Svodiče přepětí (Surge Protective Devices - SPD) jsou určeny k ochraně elektrického a elektronického zařízení proti přepětím a proudovým impulzům (způsobeným úderem blesku nebo spínacími pochody). Pro tento účel plní svodiče přepětí dvě funkce, omezují přepětí na úroveň přijatelnou pro chráněné zařízení a svádí impulsní proudy ...

Water and wastewater treatment plants are
particularly exposed lightning risks, due
to vast surface areas and exposure of
frequently isolated sites.
