2 Disturbance report
The disturbance recording function is optional. The disturbance report
menu gives the user all information recorded by the terminal for the last
10 disturbances after the last clearing of the disturbance recorder memory.
The complete menu consists of these branches:
• Information on up to the 10 last recorded disturbances
• Manual triggering of the disturbance reporting unit
• Clearing of the memory that belongs to the disturbance report
2.1 Information on
recorded disturbances
Each of the recorded disturbances displays:
• The time of disturbance, which is displayed as an internal terminal
date and time at the instant when the first of the triggering signals
starts the disturbance recording.
• Trig signal that started the recording.
• Indications that appeared during the recorded disturbance. Indica-
tions that can be recorded by the disturbance reporting unit are
selectable during the configuration procedure.
• Trip values that are displayed as phasors (RMS value and phase
angle) of the currents and voltages, before and during the fault.
2.2 Manual triggering of a
disturbance recording
Use the manual triggering of a disturbance recording submenu to get a
snapshot.
2.3 Clearing of the
disturbance report
memory
The disturbance report has a dedicated memory facility, sufficient for sav-
ing the up to the 10 latest disturbances. All this memory can be cleared
and thus prepared for a completely new set of records. The memorizing of
disturbances in the terminal follows the first in - first out (FIFO) principle.
This means that the oldest disturbance will disappear automatically from
the terminal memory when a new disturbance occurs, if 10 disturbances
are already stored in the terminal memory.
3 Service report
The Service report menu displays information about the operating condi-
tions and information about the terminal. The service report for analogue
values is available only when the transformer module option is included
in the terminal. The total report consists of these items:
• Mean values
• Phasors
• Synchronizing values
• Logical signals
• I/O modules
• Counters within the autoreclosing function
• Disturbance report
• Active group
• Internal time
