Sel SEL-421 - C37.118 Synchrophasor Protocol; Sample MET PM Command Response

Synchrophasors
C37.118 Synchrophasor Protocol
This method of data capture will always report from the exact second, even if
the time parameter is entered with fractional seconds. For example, entering
MET PM 14:14:12.200 will result in the same data capture as MET PM
14:14:12, because the relay ignores the fractional seconds.
See MET PM on page R.9.31 for complete command options, and error
messages.

C37.118 Synchrophasor Protocol
The SEL-421 complies with IEEE C37.118, Standard for Synchrophasors for
Power Systems, when Global setting MFRMT := C37.118.
The protocol is available on serial ports 1, 2, 3, and F by setting the
corresponding Port setting PROTO := PMU.
The protocol is available on the Ethernet port when EPMIP := Y.
This subsection does not cover the details of the protocol, but highlights some
of the important features and options that are available.
