It prevents nuisance tripping if networkconditions are causing "false" earth faults. In radial systems, Directional Blockingprevents nuisance tripping by blocking faults in the source direction and only responding to faults in the load direction.Distinct protection for faults in the forward and reverse direction. A forward fault mayuse a different time-current curve and settings to a reverse fault (i.e. these areindividually selectable). Both the forward protection and reverse protection areoperating at the same time.
