Annotation of standard text IEC 60871-4-ed.2.0 :
IEC 60871-4:2014 applies to internal fuses which are designed to isolate faulty capacitor elements, in order to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank or any part thereof. The object of this part of IEC 60871 is to formulate requirements regarding performance and testing and to provide a guide for coordination of fuse protection. This second edition cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The disconnecting requirements have been modified. Keywords: internal fuses, faulty capacitor elements, fuse protection LIEC 60871-4:2014 sapplique aux fusibles internes qui sont destines a isoler les elements de condensateur en defaut et permettre ainsi le maintien en service de la partie saine de lunite et de la batterie a laquelle cette unite est raccordee. Ils ne sont pas destines a se substituer a un dispositif de coupure, par exemple un disjoncteur ou une protection externe de la batterie de condensateurs ou une partie de celle-ci. La presente partie de lIEC 60871 a pour objet de formuler des exigences relatives aux performances et aux essais et de fournir un guide pour la coordination de la protection par fusibles internes. Cette deuxieme edition annule et remplace la premiere edition parue en 1996. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: Les exigences concernant la deconnexion ont ete modifiees. Mots cles: fusibles internes, elements de condensateur en defaut, protection par fusibles internes
