Full Description
IEC 62271-104:2015 is applicable to three-pole alternating current switches for rated voltages higher than 52 kV, having making and breaking current ratings, for indoor and outdoor installations, and for rated frequencies up to and including 60 Hz. This standard is also applicable to the operating devices of these switches and to their auxiliary equipment. This second edition replaces and cancels the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- the title was changed such that the voltage range now is >52 kV instead of 52 kV;
- the references have been updated;
- the comments in 17A/1063/RVC have been addressed.
This publication is to be read in conjunction withIEC 62271-1:2007, IEC 62271-100:2008, IEC 62271-102:2001 and IEC 62271-110:2012.
