Description of Commands
MET M
Use the MET M command to view power system maximum and minimum
quantities.
The reset command, MET RM, resets the Line, BK1, and BK2 maximum/
minimum metering quantities. When you issue the MET RM command, the
relay responds,
Reset Max/Min Metering (Y/N)? If you answer Y <Enter>,
the relay responds,
Max/Min Reset.
MET PM
Use the MET PM command to view the time-synchronized line quantities.
The relay must be in the high-accuracy timekeeping HIRIG mode. For more
information on high-accuracy timekeeping, see Configuring High-Accuracy
Timekeeping on page P.13.1.
If the relay is not in the high-accuracy IRIG (HIRIG) timekeeping mode, it
will respond to the MET PM command with the following message:
Aborted: A High Accuracy Time Source is Required
If Global enable setting EPMU := N, the relay will respond to the MET PM
command with:
Synchronized phasor measurement is not enabled
To request a report of the synchrophasor data at a specific time, enter the
optional time parameter as a time of day. For example, the relay will respond
to the MET PM 16:40:10 command with:
Synchronized Phasor Measurement Data Will Be Displayed at
16:40:10.000
