Sequence of Events Reports and Fault Recording
SECTION 10.
SEQUENCE OF EVENTS REPORTS
AND FAULT RECORDING
10.1
MEASURED VALUES, TRIP STATUS, SEQUENCE OF EVENTS AND
FAULT RECORDS
The Distance Protection module has its own Sequence of Event record, in addition to the System SOE.
While a trip (and other trig signals as defined in the system logic) will trigger a system event, the
distance SOE allows for more protection related details in the log. The Distance relay fault records
give even more information about the fault condition, such as pre-fault and fault analog values.
10.2
MEASURED VALUES AND TRIP STATUS
The GARD 8000 distance relay will display the measured values and trip status. The first screen
provides a summary of status and whether DFR (oscillography), SOE records and Fault Reports are
available.
