13. addition, the EMC re- quirements play ever greater role. The image alongside shows typical application insulated lightning protection system building protect the technical systems located the building. Insulator Conventional conductor S Separation distance U Induced voltage Insulated external lightning protection system with insu- lators Fastening stand Insulator Metal bracket Conventional conductor Plastic bracket Separation distance Definition the separation distance for insulators This separation distance (s) can also achieved through high-voltage-resistant insulated conductors, whereby the high-voltage-resistant conductor can be routed directly the surface the structure. This insulates the air-termination system and con- ductor system from the structure, i.1 Problem Increasingly, structures, the electrical equipment is being moved onto the roof.
