RTU and HMI Redundancy in Electrical Substations

As the substation RTU takes on more applications, such as Human-Machine-Interface (HMI), alarm annunciation, math & logic and “relay communication processing”, its need for high availability increases. Anything that takes the RTU out of service – configuration change, firmware update, or component failure – means not only loss of SCADA but also loss of local visibility, loss of non-operational data and, in some applications, loss of local control. Redundancy can address the needs for higher...
