本标准建立了测量架空电力线路和变电站电晕产生的无线电噪声的统一程序。本标准中的测量程序也适用于其他电力线噪声源，如间隙和谐波；然而，大多数预防信息、分析和数据绘制技术主要是针对电晕放电编写和开发的。这些程序不适用于测量断路器或断开开关操作期间发生的瞬态无线电噪声源。程序适用于0.010 MHz至1000 MHz的频率范围；然而，重点是标准调幅广播（0.535 MHz至1.605 MHz）和电视广播（54 MHz至72 MHz、76 MHz至88 MHz、174 MHz至216 MHz和470 MHz至698 MHz）频段。 本标准适用于交流和直流输电线路及变电站。

This standard establishes uniform procedures for the measurement of radio noise generated by corona from overhead power lines and substations. Measurement procedures in this standard are also valid for other power-line noise sources such as gaps and harmonics; however, most of the precautionary information, analysis, and data plotting techniques were written and developed primarily for corona discharges. The procedures are not valid for measuring transient radio noise sources that occur during breaker or disconnect switching operations. The procedures apply in the frequency range of 0.010 MHz to 1000 MHz; however, the emphasis is on the standard amplitude-modulation broadcasting (0.535 MHz to 1.605 MHz) and television broadcasting (54 MHz to 72 MHz, 76 MHz to 88 MHz, 174 MHz to 216 MHz, and 470 MHz to 698 MHz) bands. This standard is applicable to both ac and dc transmission lines and substations.
