rate. With firmware 6.0 a maximum of two PMUs can be set to a reporting rate of 120 Hz for a 60 Hz system (or 100Hz for
a 50 Hz system) and each aggregator can be configured to support a TCP or a UDP connection to a client allowing the UR
to support a total of two TCP connections or two UDP connections or a combination of a TCP and a UDP connection per
aggregator for real-time data reporting. Also note that if hard fiber is used it will have no impact on this specification.
Precise IRIG-B input is vital for correct synchrophasor measurement and reporting. A DC level shift IRIG-B receiver
must be used for the phasor measurement unit to output proper synchrophasor values.
NOTE
The PMU settings are organized in five logical groups as follows.
