    • An inductive coupler 33 provides an interface between a power line and a communication device which communicates vi the power line The power line operates at a potential between four and 140 kilovolts while accommodating a current havi a frequency between 45 and 65 hertz, and the communication device operates substantially at ground potential The inductive coupler includes a split ferrite core 10, 13 having material selected to provide a substantially flat frequency response between one and 50 megahertz The coupler also includes a clamping mechanism 17, 27 allowing the inductive coupler to clamp around the power line or around a utility line connected to the power line Further, the coupler includes a least one lead 77 for communicatively connecting the inductive coupler to the communication device The inductive coupl forms an air gap 8 when the inductive coupler is clamped If the coupler is insulated, the insulation is also used for the air gap.
    • 电感耦合器33提供电力线和与电力线通信的通信装置之间的接口。电力线工作在四到140千伏之间的电位,同时容纳45至65赫兹之间的电流,并且通信装置 感应耦合器包括分开的铁氧体磁芯10,13,其具有被选择为提供在一个和50兆赫之间的基本上平坦的频率响应的材料。该耦合器还包括夹紧机构17,27,允许电感耦合器围绕电力夹紧 线路或连接到电力线的公用设施线周围。此外,耦合器包括用于将电感耦合器通信地连接到通信装置的至少一个引线77.当电感耦合器被夹紧时,感应耦合形成气隙8.如果耦合器绝缘 ,绝缘也用于气隙。
