RED670 的具体功能和特点可能包括:
快速、准确的故障检测
高度的可靠性和稳定性
可配置的保护逻辑，以适应不同的电力系统需求与其他ABB保护和控制设备的兼容性
远程监控和配置功能
在正常工作情况下，RED670 流入母线的电流和等于从该节点流出的电流，即母线差动保护的差动电流为零。如果母线发生故障，差动电流将大于零，母线差动保护将会动作切除故障。
Specific functions and features of the RED670 may include:
Fast and accurate fault detection
High reliability and stability
Configurable protection logic for compatibility with other ABB protection and control devices to suit different power system needs
Remote monitoring and configuration functions
Under normal working conditions, the current flowing into the bus of RED670 is equal to the current flowing out of the node, that is, the differential current of the differential protection of the bus is zero. If the busbar fails, the differential current will be greater than zero, and the busbar differential protection will act to remove the fault.
