6.3.3 VOLTAGE
Line and phase voltage magnitudes and phasors for the bus VT inputs are displayed along with sequence
components. All messages pertaining to phase voltages A-N, B-N, and C-N are only displayed if the
VT CON-
NECTION TYPE
setpoint is programmed to
wye
.
NEG SEQ CURRENT:
0 A 0° Lag
Displays the calculated negative sequence current RMS phasor.
ZERO SEQ CURRENT:
0 A 0° Lag
Displays the calculated zero sequence current RMS phasor.
POLARIZING CURRENT:
0 A 0° Lag
Displays the measured polarizing current RMS phasor
