Computer-based protection devices are capable of continuous self diagnosis and will self check and alarm at the onset of the first indication of any malfunction, including intermittent failures. Another advantage is the versatility available on a computer-based system that is not available on hard-wired systems. Another advantage is the ability to share voltage and current inputs among various microcomputer systems to increase the level of redundancy and reliability of a computer-based relay system. To obtain experience in the field of microprocessor relaying, American Electric Power Service Corp. initiated the development of its first computer-based digital distance-relay system in 1971, which has been field tested and approved. Developent has now progressed to the point where a symmetrical component relay has been designed and tested, and will be installed at the Matt Funk Station, in Roanoke, Virginia in early 1980.
