Each time a Maintenance Report is generated, an event is also created. The event simply
states that a report was generated, with a corresponding time stamp.
1.2.9 Setting Changes
Changes to any setting within the relay are logged as an event. Two examples are shown in
the following table:
Displayed Text in Event Record
Control/Support Setting C & S Changed
Group 1 / 2 / 3 or 4 Change Group 1, 2, 3 or 4 updated
Disturbance setting Disturbance recorder
Active group change Active group changed
Note: Control/Support settings are communications, measurement, CT/VT ratio settings etc,
which are not duplicated within the four setting groups. When any of these settings
are changed, the event record is created simultaneously. However, changes to
protection or disturbance recorder settings will only generate an event once the
settings have been confirmed at the ‘setting trap’.
1.2.10 Resetting of Event / Fault Records
If it is required to delete either the event, fault or maintenance reports, this may be done from
within the ‘RECORD CONTROL’ column.
1.2.11 Viewing Event Records via MiCOM S1 Agile Support Software
When the event records are extracted and viewed on a PC they look slightly different than
when viewed on the LCD. The following shows an example of how various events appear
when displayed using MiCOM S1 Agile:
