TESTING
The relay must be in test mode to use the PMU test mode. That is, the
"Enabled," and the
During the PMU test mode, the physical channels (VA, VB, VC, VX, IA, IB, IC, and IG), frequency, and rate of change of
frequency are substituted with user values, while the symmetrical components are calculated from the physical channels.
The test values are not explicitly marked in the outgoing data frames. When required, it is recommended to use the user-
programmable digital channels to signal the IEEE C37.118 client that test values are being sent in place of the real
measurements.
The UR Synchrophasor Implementation defines a test mode that sends a pre-defined set of synchrophasors out over the
communication channel when the test mode function setting is enabled. In test mode, the following actions take place:
•
The Data Invalid / Test Mode bit (bit 15 in the STAT word) is set
•
The Sim bit in all output datasets is set
