Integrated substation control, monitoring, and protection system
ekorRCI
Ormazabal
Power Networks Automation
Integrated control unit for the incoming feeder functional unit. It consists of an electronic relay with current sensors. Having full communications capabilities, it communicates with the remote unit for the remote control functions, and has the capacity for local control.
