Command Definitions
MET (Meter)
Access Levels 1, 2
The MET command displays instantaneous magnitudes and phase angles of
the following:
Current magnitudes are displayed in primary amperes. The SEL-587Z reports
the phase angles referenced to IA (IA phase angle = 0, positive phase angles
leading).
To view sequential instantaneous metering values, enter the command:
=>MET n <Enter>
where n is an optional parameter to specify the number of times to repeat the
meter display. n may range from 1 to 32767. If n is not specified, the relay
displays the meter report once:
