A system including a number of subsystems having dedicated protection units which are dedicated to the protection of specific transmission lines and associated power equipment, each subsystem having stand-alone capability. The subsystems are interfaced to a central computer through a remote control communications interface unit. Each subsystem includes a microprocessor which interfaces with the corresponding transmission line or associated power equipment to be protected through converters, sensors, contacters, direct digital control equipment and the like. The central computer is capable of performing real time modification by addressing each subsystem to change local protection parameters thereof to fit system needs. The system is totally digital, lending itself to integration into other digital control apparatus.

A method of monitoring and controlling the respective operating conditions of a plurality of electrical power transmission structures at a corresponding plurality of locations remote from each other comprising: sensing the operating condition of the power transmission structure at each of the locations; digitizing the information corresponding to the sensed operating condition from each location; communicating the digitized information to a microprocessing station at each location; processing the digitized information with a predetermined algorithm to cause the generation of signals corresponding to the operating condition of the corresponding power transmission structure; communicating the signals from each microprocessing station to a central processing region independently of the communication of the signals from the microprocessing stations of the other locations; and changing the operating conditions of the transmission structure at a location corresponding to a predetermined operating condition detected by the receipt of digitized information at the corresponding microprocessing station.
