ASCII Command Reference
Command Description
MET D
Use the MET D command to view the demand and peak demand quantities.
NOTE: Not all SEL-400 series relays
support demand metering.
The reset command (MET RD) resets the demand metering quantities. When
you issue the MET RD command, the relay responds,
Reset Demands (Y/N)?.
If you answer Y <Enter>, the relay responds,
Demands Reset.
The reset command, MET RP, resets the peak demand metering quantities.
When you issue the MET RP command, the relay responds,
Reset Peak Demands
(Y/N)?
. If you answer Y <Enter>, the relay responds, Peak Demands Reset.
MET M
Use the MET M command to view power system maximum and minimum quantities.
NOTE: Not all SEL-400 series relays
support maximum/minimum
metering.
The reset command, MET RM, resets the maximum/minimum metering quanti-
ties. 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 quantities. The relay
must be in the high-accuracy timekeeping HIRIG or HPTP mode. For more infor-
mation on high-accuracy timekeeping, see Section 11: Time and Date Manage-
ment.
NOTE: Not all SEL-400 series relays
support synchrophasors.
