IEC 62271-101:2021主要适用于IEC 62271-100范围内的交流断路器。本标准规定了交流断路器试验的一般规则，以及IEC 62271-100:2021第7.102条至第7.111条所述试验范围内的通断能力试验的一般规则。 已经证明，根据IEC 62271-100的要求，综合测试是测试高压交流断路器的一种经济且技术上正确的方法，并且等同于直接测试。 所描述的方法和技术是一般使用的方法和技术。本文件的目的是为综合测试和结果的正确评估建立标准。这些标准将确定试验方法的有效性，而不限制试验电路的创新。 本第三版取消并取代2012年出版的第二版和修订版1: 2017本版为技术修订版。 本版本包括与第二版相关的以下重大技术变更: a） 与IEC 62271-100:2021第三版保持一致； b） 使用合成试验所用的最新方法和技术更新本文件。

IEC 62271-101:2021 mainly applies to AC circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing AC circuit-breakers, for making and breaking capacities over the range of test duties described in 7.102 to 7.111 of IEC 62271-100:2021, by synthetic methods. It has been proven that synthetic testing is an economical and technically correct way to test high-voltage AC circuit-breakers according to the requirements of IEC 62271-100 and that it is equivalent to direct testing. The methods and techniques described are those in general use. The purpose of this document 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. This third edition cancels and replaces the second edition published in 2012 and Amendment 1:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the second edition: a) alignment with the third edition of IEC 62271-100:2021; b) update this document with the last methods and techniques used for synthetic tests.
