Use this menu to display the information recorded by the REx 5xx terminal for the 10
latest disturbances, these commands are available:
•
Display information of a disturbance.
•
Calculate the distance to fault.
•
Manually trigger the disturbance reporting unit.
•
Clear the disturbance report memory.
•
To view the complete disturbance report, including the result of the event recorder
and the disturbance recorder, use a front-connected PC or the SMS or SCS.

A disturbance will show:
•
7KHWLPHRIGLVWXUEDQFH
, which is defined as the local terminal date and time when
the first triggering signal started the disturbance recording.
•
7KHWULJVLJQDO
, which started the recording.
•
,QGLFDWLRQV
, activated during the fault duration. Indications to be recorded are se-
lected during the terminal configuration procedure.
The fault locator will also report:
•
)DXOWORFDWLRQ
, provides information about the distance to the fault and the fault
loop used for the calculation.
•
7ULSYDOXHV
, are displayed as phasors (RMS value and phase angle) of the currents
and voltages, before and during the fault.
&DOF'LVW7R)OW
Possible to recalculate the distance to fault with a different fault loop or with different
fault locator setting parameters. The recalculation is enabled since trip values are avail-
able for each disturbance that caused a phase-selective trip of the distance protection
function.
