Protection against lightning - Part 4: Electrical and electronic systems within structures

IEC 62305-4:2010(E) provides information for the design, installation, inspection, maintenance and testing of electrical and electronic system protection (LPM) to reduce the risk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure. This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 1) Isolating interfaces capable of reducing conducted surges on lines entering the structure are introduced. 2) Minimum cross-sections for bonding components are slightly modified. 3) First negative impulse current is introduced for calculation purposes as electromagnetic source of harm to the internal systems. 4) Selection of SPD with regard to voltage protection level is improved to take into account oscillation and induction phenomena in the circuit downstream of SPD. 5) Annex C dealing with SPD coordination is withdrawn and referred back to SC 37A. 6) A new informative Annex D is introduced giving information on factors to be considered in the selection of SPDs.

Protection contre la foudre - Partie 4: Réseaux de puissance et de communication dans les structures

La CEI 62305-4:2010 fournit des informations relatives à la conception, à l'installation, à l'inspection, à la maintenance et aux essais d'une installation de protection de réseau de puissance et de communication (MPF) visant à réduire le risque de défaillances permanentes dû aux impulsions électromagnétiques de foudre (IEMF) dans une structure. Cette seconde édition annule et remplace la première édition, publiée en 2006, dont elle constitue une révision technique. La présente édition comprend les modifications techniques importantes suivantes par rapport à la précédente édition: 1) Introduction d'interfaces d'isolement capables de réduire les chocs conduits sur les services pénétrant dans la structure. 2) Légère modification des sections minimales des composants de liaison. 3) Introduction d'un premier courant pulsé négatif à des fins de calcul, comme source électromagnétique de dégradation des réseaux internes. 4) Amélioration du choix du parafoudre par rapport au niveau de protection contre les surtensions, afin de tenir compte de l'existence de phénomènes d'oscillation et d'induction dans le circuit en aval du parafoudre. 5) Suppression de l'Annexe C traitant de la coordination des parafoudres avec renvoi au SC 37A. 6) Introduction d'une nouvelle Annexe informative D fournissant des informations sur les facteurs à prendre en compte dans le choix des parafoudres. La présente version bilingue (2012-06) correspond à la version anglaise monolingue publiée en 2010-12.

Zaščita pred delovanjem strele - 4. del: Električni in elektronski sistemi v zgradbah (IEC 62305-4:2010, spremenjen)

Ta mednarodni standard zagotavlja informacije za projektiranje, namestitev, nadzor, vzdrževanje in preskušanje zaščite električnih in elektronskih sistemov (ESP) in ukrepov za zmanjšanje tveganja za trajne okvare zaradi elektromagnetnih impulzov strele (LEMP) v zgradbi. Ne zajema zaščite pred elektromagnetnimi motnjami zaradi delovanja strele, ki lahko povzročijo okvaro elektronskega sistema. Informacije, navedene v dodatku A, pa se lahko kljub temu uporabijo za vrednotenje takih motenj. Ta osnutek mednarodnega standarda ne obravnava podrobnosti projektiranja samih električnih in elektronskih sistemov.
