REF 541/3/5 馈线保护终端用于中压电网的线路保护、控
制、测量和监视等功能。保护终端可用于不同电压等级的
中性点接地、小电阻接地、中性点不接地和谐振接地的网
络。同时既适用于辐射网也用于环状网，既适用于单端供
电系统也可用于多端供电的线路。
保护功能包括：带或不带方向的相间过流、接地、过电压、
低电压、热过负荷保护，频率保护，断路器失灵保护及自
动重合闸功能。其他功能包括：电流，电压，频率，功率
因数，有功和无功功率以及电能的测量，断路器状态监
视、跳闸回路监视等功能，保护单元支持RTD/ 模拟量输
入模块。
REF 541/3/5具有两个独立的且可同时运行的通讯端口，
RS-485 接口支持LON 及SPA 协议，通讯波特率最大可
至1.2Mpbs。RS-232接口支持Modbus RTU/ASCII，DNP3.
0，IEC 60870-5-103 及SPA 协议，通讯波特率最大可
至19.2 kbps。这些端口可以方便用户简易快速地接入
各类厂家的后台系统。
免费的基于Windows 环境下的CAP 501 软件能使用户全

面了解相关继电器的所有信息，且能方便快捷地整定保护
