本标准涵盖了额定电压高于1000伏且基于对称电流的交流高压断路器瞬态恢复电压要求的应用指南。这些断路器开断装置的容量限制在很大程度上取决于瞬态恢复电压。应用指南未包含在其他现有断路器标准中。

This standard covers the application guide for transient recovery voltage requirements for ac high-voltage circuit breakers rated above 1000 volts and on a symmetrical current basis. The capability limits of these circuit breaker interrupting devices are determined largely by the transient recovery voltages. The guide for application is not included in other existing circuit breaker standards.
