本标准适用于同步电机完整励磁系统及其部件的高电位测试。还包括暴露在励磁系统应力下的辅助装置。此类辅助装置的示例包括温度指示器、传感器、仪表等。本标准不包括同步电机磁场绕组或磁场断路器和放电电阻器。

This standard applies to high-potential testing of complete excitation systems and their components for synchronous machines. Also included are auxiliary devices that are exposed to excitation system stresses. Examples of such auxiliary devices are temperature indicators, transducers, meters, etc. This standard does not cover the synchronous-machine field winding or field circuit breaker and discharge resistor.
