本指南旨在为断路器的综合测试提供依据（见ANSI/IEEEC37.04-1979[2]），并建立测试标准，以证明单相断路器的短路电流额定值。 我们承认，还有其他测试要求（如电容器切换或线路下降），但这些要求将留作将来考虑。 本指南包含用于演示中断能力的典型电路。这些电路是通用电路，其包含不应排除开发额外电路以展示特定能力。

This guide is intended to provide a basis for synthetic testing of circuit breakers (see ANSI/IEEEC37.04-1979 [2]) and to establish the criteria for testing to demonstrate the short-circuit current rating of circuit breakers on a single phase basis. It is recognized that other test requirements exist (such as capacitor switching, or line dropping) but they will be reserved for future consideration. The guide contains typical circuits for demonstrating interrupting capability. These circuits are those in general use and their inclusion should not exclude the development of additional circuits to demonstrate specific capabilities.
