The present invention relates to a system for protecting and controlling main-circuit components of an electricity transmission substation. The system includes devices for digital data output, protection-and-controlling, component controlling-and-monitoring, and communication. The digital data output devices input analogue AC electric values and output digital data. The protection-and-controlling devices input the data from the digital data output devices, and further control, monitor, and protect the substation main-circuit components. The component controlling-and-monitoring devices receive commands from the protection-and-controlling devices or from the substation controlling-and-monitoring equipment, and further control and monitor the substation main-circuit components. The devices for digital data output, the protection-and-controlling, and component controlling-and-monitoring are disposed near or within their corresponding substation main-circuit components.
