IEC 62271-101:2006

Applies to a.c. circuit-breakers within the scope of IEC 60056 (Clause 1). It provides the general rules for testing a.c. circuit-breakers, for making and breaking capacities over the range of test-duties described in Subclauses 6.102 to 6.111 of IEC 60056, by synthetic methods. The purpose of this standard is to establish criteria for synthetic testing and for the proper evaluation of results. Such criteria will establish the validity of the test method without imposing restraints on innovation of test circuitry.

IEC 62271-101:2012 mainly applies to a.c. circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing a.c. circuit-breakers, for making and breaking capacities over the range of test duties described in 6.102 to 6.111 of IEC 62271-100:2008, by synthetic methods. This second edition cancels and replaces the first edition published in 2007 and its Amendment 1 published in 2011. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the first edition: - addition of the new rated voltages of 1 100 kV and 1 200 kV; - revision of Annex F regarding circuit-breakers with opening resistors; - alignment with the second edition of IEC 62271-100:2008 and its Amendment 1 (2012). This publication is to be read in conjunction with IEC 62271-100:2008.
