本推荐规程适用于检测电气设备或其部件绝缘中发生的局部放电，以及在施加交流试验电压时测量端子处的相关视在电荷。附录E中讨论了使用直流电压的局部放电试验。 本推荐做法仅涉及一般原则。如果包括电晕检测和测量程序的标准文件涵盖了特定仪器，则应遵循这些标准。

This Recommended Practice applies to the detection of partial discharges occurring in the insulation of electrical apparatus or its components, and to the measurement of the associated apparent charge at the terminals, when an alternating test voltage is applied. Tests for partial discharges using direct voltage are discussed in Appendix E. This Recommended Practice is concerned with general principles only. Where specific apparatus is covered by standards documents that include corona detection and measurement procedures, those standards should be followed.
