The fault locator has influence over information in the
EVENT
and
LOCAT
columns. If the fault locator is enabled (enable setting EFLOC = Y), the fault
locator will attempt to run if the event report is generated by a trip (assertion
of TRIP Relay Word bit) or other programmable event report trigger condition
(SEL
OGIC®
control equation setting ER).
If the fault locator runs successfully, the location is listed in the
LOCAT
column,
and the event type is listed in the
EVENT
column:
If a trip occurs in the same event report, a
T
is appended to the event type (e.g.,
AG T
).
If the fault locator does not run successfully,
$$$$$$$
is listed in the
LOCAT
column. If the fault locator is disabled (enable setting EFLOC = N), the
LOCAT
column is left blank. For either of these cases where the fault locator does not
run, the event type listed in the
EVENT
column is one of the following:
