  • Patent number: 4161027
    Abstract: 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.
