1.2.1.8 Setting changes
Changes to any setting within the relay are logged as an event. Two examples are shown in
the following table:
Type of setting change Displayed text in event record Displayed value
Control/Support Setting C & S Changed 22
Group # Change Group # Changed #
Where # = 1 to 4
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’.
1.2.2 Resetting of event/fault records
If it is require
d to delete either the event, fault or maintenance reports, this may be done from
within the RECORD CONTROL column.
1.2.3 Viewing event records via MiCOM S1 Studio support software
Whe
n 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 Studio:
