The continuous monitor logic is intended to detect the operation of any tripping element that has operated under normal
load conditions; that is, when the disturbance detector has not operated. Because all tripping is supervised by the distur-
bance detector function, no trip will be issued under these conditions. This could occur when an element is incorrectly set
so that it may misoperate under load. The continuous monitor can detect this state and issue an alarm and/or block the trip-
ping of the relay.
