标准摘要
[中文适用范围]： 建立了插入高压交流输电线路的设备的定义、要求、测试方法和额定值，以防止在所有电力系统条件下载波信号功率的过度损失，并最大限度地减少来自载波的干扰 [外文原描述]： Applies to line traps inserted into high-voltage a.c. transmission lines that prevent undue loss of carrier signal power in the range 30 kHz to 500 kHz under all power system conditions, and that minimize interference from carrier signalling systems on adjacent transmission lines.
英文名称Line traps for a.c. power systems
