The root issue is an assessment of the consequences of falsely tripping when there is no HIF or not tripping when there is a HIF. If a feeder is not tripped or patrol action started for a downed conductor, then possible loss of life, legal liability, or property damage may result. If a feeder is tripped unnecessarily, then possible traffic hazards (due to inoperative traffic signals), medical emergencies, reduced reliability, and loss of load may result. Each utility must evaluate their use of HIF detectors (including trip vs. Alarm) based on their own situation.
