The example event summary in Figure SECTION 12: .1 corresponds to the full-length standard
15-cycle event report in Figure SECTION 12: .2 (
Note : Figure SECTION 12: .2 is on multiple
pages):

Figure SECTION 12: .1: Example Event Summary
The control sends event summaries to all serial ports with setting AUTO = Y each time an event
triggers.
The latest twenty-eight 15-cycle or fourteen 30-cycle event summaries are stored in nonvolatile
memory and are accessed by the HIS (Event Summaries/History) command.
Event Type
The “Event:” field shows the event type. The possible event types and their descriptions are
shown in the table below. Note the correspondence to the preceding event report triggering
conditions (see
Standard Event Report Triggering in this section).
Table SECTION 12: .1: Event Types
Event Type Description
AG, BG, CG Single phase-to-ground faults. Appends T if TRIP asserted.
ABC Three-phase faults. Appends T if TRIP asserted.
AB, BC, CA Phase-to-phase faults. Appends T if TRIP asserted.
ABG, BCG, CAG Two phase-to-ground faults. Appends T if TRIP asserted.
TRIP Assertion of Relay Word bit TRIP (fault locator could not
operate successfully to determine the phase involvement, so
only TRIP is displayed).
ER SEL
OGIC
Control Equation setting ER. Phase involvement is
indeterminate.
TRIG Execution of TRIGGER command.
PULSE Execution of PULSE command.
The event type designations AG through CAG in Table SECTION 12: .1 only are entered in the
“Event:” field if the fault locator operates successfully. If the fault locator does not operate
successfully, just TRIP or ER is displayed.
