美国SEL451产品系列选型介绍见附件
美国SEL公司（Schweitzer Engineering Laboratories, Inc.）自1984年以来致力为客户设计和生

产*数字产品和系统来提高电力系统的可靠性和安全性。
SEL-700G保护继电器通过自动同步装置、灵活的I/ O以及*通信，SEL-700G继电器是公用事业设施和工业发电机保护的解决方案。使用SEL-700G继电器，可提供全面的发电机主后备保护。SEL-700G 为同步发电机提供了全面的保护和同步解决方案。淘汰了复杂而昂贵的独立同步器组件。把同步功能集成到发电机保护继电器中可提供成本效益及可靠的解决方案。不需切割或在现有的切口钻孔，只要用小型组件及多种安装适配器，就可轻易升级保护，采用Modbus，DNP3，IEC 61850，镜像位通信，DeviceNet和其他协议，就可迅速集成入serial-或基于以太网的通信，易于通信 -选择单股或双股铜线或光纤以太网端口，或串行通信设备，并选择多个协议，包括Mirrored Bits 通信和 IEC 61850。挑选多个 Modbus TCP 或 Modbus 连续会话来自定义您的应用配置。利用 DNP3 串行或 DNP3 LAN/WAN 协议。为美国SEL700G系列。
