6.3.6 POWER
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 setpoint
VT CONNECTION TYPE
is set to
none , 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:
P

= Phase CT Primary
