Annotation of standard text IEC 61481-1-ed.1.0 :
IEC 61481-1:2014 is applicable to portable phase comparators of capacitive type to be used on electrical systems for voltages exceeding 1 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to single-pole phase comparators of capacitive type operating with a memory system up to 36 kV a.c., and two-pole phase comparators of capacitive type operating with a wireless connection up to 245 kV a.c. This standard is applicable to phase comparators of capacitive type used in contact with the bare conductive parts to be compared as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard. A device that is designed to provide other functions than phase comparison is a different device and is not covered by this standard. For example a device designed to be also used as a voltage detector is not covered by this standard. This first edition, together with the first edition of IEC 61481-2, cancels and replaces the first edition of IEC 61481 published in 2001, Amendment 1:2002 and Amendment 2:2004. This edition constitutes a technical revision including the following major changes: - split of the standard in two parts; - extension of the scope to include two-pole phase comparators operating with a wireless connection up to 245 kV a.c.; - review of the requirements for indication; - introduction of a requirement for a new marking "LU" for limited use; - and revision of existing annexes. The contents of the corrigendum of July 2015 have been included in this copy. LIEC 61481-1:2014 est applicable aux comparateurs de phase portatifs de type capacitif pour une utilisation sur des installations electriques a des tensions alternatives superieures a 1 kV et a des frequences de 50 Hz et/ou 60 Hz. La presente norme est applicable aux comparateurs de phase unipolaires de type capacitif fonctionnant avec un systeme de memoire, jusqua une tension alternative de 36 kV, et aux comparateurs de phase bipolaires de type capacitif fonctionnant avec une liaison sans fil, jusqua une tension alternative de 245 kV. La presente norme est applicable aux comparateurs de phase de type capacitif utilises au contact avec les parties nues conductrices a comparer au dispositif complet incluant son element isolant ou au dispositif separe adaptable sur une perche isolante qui, en tant quoutil separe, nest pas couverte par la presente norme. Un dispositif concu pour realiser dautres fonctions que la comparaison de phase est un dispositif different et nest pas couvert par la presente norme. Par exemple, un dispositif concu pour etre aussi utilise comme detecteur de tension nest pas couvert par la presente norme. Cette premiere edition, avec la premiere edition de lIEC 61481-2, annule et remplace la premiere edition de lIEC 61481 parue en 2001, lAmendement 1:2002 et lAmendement 2:2004. Cette edition constitue une revision technique qui inclut les modifications majeures suivantes: - division de la norme en deux parties; - extension du domaine dapplication permettant de couvrir les comparateurs de phase bipolaires fonctionnant avec une liaison sans fil jusqua des tensions alternatives de 245 kV; - la revision des exigences relatives a lindication; - lintroduction dune exigence relative a un nouveau marquage "LU" pour une utilisation limitee; - et la revision des annexes existantes. Le contenu du corrigendum de juillet 2015 a ete pris en consideration dans cet exemplaire.
