Surge protection mandatory all building install- ations! Insulation coordination must carried out all new or expanded electrical systems. DIN VDE 0100-443: WHEN surge protection neces- sary On all newly planned buildings and changes expan- sions existing electrical systems. Surge protection devices (at least type type 2+3) prevent insu- lation failure, thus avoiding short circuits and fires. IEC 60364-4-44: "The erection surge protective devices (SPDs) should ensure a voltage limitation according the in- sulation coordination, order avoid dangerous spark formation and resulting fires. Surge protection prevents the insulation failure through high voltages and avoids fires due short circuiting. DIN VDE 0100-534: HOW and WHICH measurements are required? Surge protection installed close pos- sible the supply point the electrical system.1 Surge protection part equipotential bonding In Germany, surge protection has been reregulated by the standards IEC 60364-4-44 and IEC 60364-5-53 and has been obligatory since October 2016.TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 Type surge protection device the distribution 1. Electric- al planners and installation engineers must inform cli- ents this necessity. For this reason, surge protection devices (type type 1+2) able carry lightning current must used the supply point the electrical system.9. This also applies the sup- ply cable run between the last mast the exposed cable and the building earth cable. Protection mandatory for exposed cables! Buildings supplied exposed cables are risk from partial lightning currents.“ TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 53 Chapter General introduction . the distance between the surge protection device and the device protected involves cable length of more than metres, additional measures are re- quired
