Abstract :
This paper lays the ground work for the statistical determination of the reliability of protective relay systems found in electric power systems. The reliability problem has two conflicting requirements: 1) failure to operate in the presence of a fault and 2) unnecessary operation when a fault occurs that the relay or relay system was set to ignore. It is not often treated in reliability literature.
