适用于在交流电压高达400 Hz或直流电压下进行试验时，测量电气设备、部件或系统中发生的局部放电。定义要测量的量，并描述可能使用的测试和测量电路。本标准的规定应用于起草与特定功率设备的局部放电测量有关的规范。本标准与IEC 60270:2000相同，并根据IEC 60270:2000复制。

Applies to the measurement of partial discharges which occur in electrical apparatus, components or systems when tested with alternating voltages up to 400 Hz or with direct voltage. Defines the quantities to be measured and describes test and measuring circuits which may be used. It is intended that the provisions of this Standard should be used in the drafting of specifications relating to partial discharge measurements for specific power apparatus. This Standard is identical to and has been reproduced from IEC 60270:2000.
