The CURR column shows the magnitude of the maximum phase-current measured at the
middle of the fault in primary amperes.
The TARGETS column shows fault targets for faults which cause a trip to occur. If no trip
occurred for the fault or the event is not a fault, this column is blank. These targets are the
same as SEL-267D relay front panel targets.
IRIG
The IRIG command directs the relay to read the demodulated IRIG-B time code input if
present at J201 on the rear panel.
If the time code is successfully read, the interval clock/calendar time and date are updated to
the time code reading, and the relay transmits a message consisting of relay ID string, date,
and time. An example of a successful read is shown below.
If no time code signal is present at the AUX port or if the time code cannot be successfully
decoded, the relay sends the error message
"
IRIGB DATA ERROR.
"
An unsuccessful read
causes the following output:
Note:
When the relay is connected to a time code signal via the AUX port it is normally
unnecessary to synchronize using this command; the relay synchronizes automatical-
ly every few minutes. The command is provided as a test and setup feature, to
avoid waiting for automatic synchronization during test and installation.
METER n
The currents, demand currents, peak demand currents, voltages, and real and reactive power
are displayed in primary quantities of amperes, kilovolts, megawatts, and megavars. An
example is shown below.
