PLUS
LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 527
When set to “Trigger/Re-Trigger” or “Re-Trigger Only,” the disturbance recorder is re-
triggered if the signal is still asserted at the end of the trigger period. The resulting record
contains fault data only. A re-trigger is re-generated at the end of a disturbance record if
the signal is still asserted and if the number of re-triggers is less than the value specified
by the
Maximum Re-Triggers setting.
