TESTING
During the PMU test mode, the physical channels (VA, VB, VC, VX, IA, IB, IC, and IG), frequency, and rate of change of fre-
quency 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-pro-
grammable digital channels to signal the C37.118 client that test values are being sent in place of the real measurements.
