The actual values messages for three-phase and Phase A power are shown above.
Similar power messages follow for Phases B and C.
The relay calculates and displays the real, reactive, and apparent power of the
system. Both three phase and single phase quantities are given. The relationship of
these power quantities is illustrated in the power plane, as shown in the power
quantity relationships figure that follows. If the
all three phase quantities are displayed as zero and all single phase quantities
disappear. All power quantities auto-range to show units appropriate to the nominal
power which is defined as:
