Annotation of standard text IEC/TR 61641-ed.3.0 :
IEC TR 61641:2014 gives guidance on the method of testing of ASSEMBLIES under conditions of arcing in air due to an internal fault. The purpose of this test is to assess the ability of the ASSEMBLY to limit the risk of personal injury, damage of ASSEMBLIES and its suitability for further service as a result of an internal arcing fault. This third edition cancels and replaces the second edition published in 2008. It constitutes a technical revision. This third edition includes the following significant technical changes with respect to the previous edition: - arcing classes to define the different forms of protection provided against arcing faults; (i) personnel protection, (ii) damage restricted to part of the ASSEMBLY, and (iii) ASSEMBLY suitable for limited further service.; - two levels of personnel protection afforded by ASSEMBLIES under arcing fault conditions; (i) for ASSEMBLIES installed in areas where access to the ASSEMBLY is restricted to skilled persons, and (ii) for ASSEMBLIES installed in areas where the area is accessible to ordinary persons; - option of individually insulating all live conductors to make the complete ASSEMBLY an arc ignition protected zone (referred to as an arc free zone in previous editions of the Technical report); - arc fault protection front, back and sides of an ASSEMBLY as the normal requirement; - minimum performance requirements for arc ignition protected zone. LIEC TR 61641:2014 donne des lignes directrices sur les methodes dessai des ENSEMBLES dappareillage en conditions darc dus a un defaut interne se developpant dans lair. Le but de cet essai est devaluer laptitude de lENSEMBLE a limiter le risque de blessure corporelle et les dommages aux ENSEMBLES, ainsi que ladaptabilite au service consecutif et posterieur a un arc du a un defaut interne. Cette troisieme edition annule et remplace la deuxieme edition publiee en 2008. Cette edition constitue une revision technique. Cette troisieme edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - les classes darc pour definir les differentes formes de protection fournies contre les defauts darc; (i) protection individuelle, (ii) dommage limite a une partie de lENSEMBLE et (iii) ENSEMBLE adapte a un service posterieur au defaut limite; - deux niveaux de protection individuelle offerts par les ENSEMBLES dans des conditions de defaut darc; (i) pour les ENSEMBLES installes dans des zones ou lacces a lENSEMBLE est limite aux personnes formees et (ii) pour les ENSEMBLES installes dans des zones ou lacces est possible pour les personnes ordinaires; - loption disolation individuelle de tous les conducteurs sous tension afin de faire de lENSEMBLE complet une zone protegee a la creation darc de defaut (designee comme une "zone exempte darc" dans les editions precedentes du rapport technique); - la protection contre le defaut darc a lavant, a larriere et sur les cotes dun ENSEMBLE comme exigence normale; - les exigences de performances minimales pour la zone a probabilite marginale de creation darc.
