Synchrophasors The relay can function as a phasor measurement unit (PMU) at
the same time as it provides best-in-class protective relay
functions.
C37.118 message format allows up to eight current and eight
voltage synchronized measurements, up to 60 messages per
second (on a 60 Hz nominal power system). Two choices of
filter response, settable angle correction, and choice of
numeric representation makes the data usable for a variety of
synchrophasor applications.
SEL Fast Operate commands are available on the synchropha-
sor communications ports, allowing control actions initiated
by the synchrophasor processor.
SEL Fast Message Synchrophasor format is also available,
with up to four current and four voltage synchronized mea-
surements.
