The algorithm is in “Normal” state when it detects no abnormal activity on the power system. While in the “Normal” state,
any one of several power system events (a high output of the Expert Arc Detector, a significant loss of load, or a Hi-Z over-
current) cause the algorithm to move to the “Coordination Timeout” state, where it remains for the time specified by the
OC
PROTECTION COORD TIMEOUT
setting. Following this interval, the algorithm moves into its “Armed” state. The criteria for
detecting arcing or a downed conductor are:
1.
the Expert Arc Detector Algorithm's output reaches a high level enough times, and
2.
its high level was last reached when the algorithm's state was “Armed”.
The “Arcing Sensitivity” setting determines what level constitutes a “high” output from the Expert Arc Detector Algorithm,
and the number that constitutes what “enough times” means. If these criteria are met, the algorithm temporarily moves to
either the “Arcing” state or the “Downed Conductor” state, the difference being determined by whether or not there was a
