The measured values of line and phase voltage magnitudes and phasors for the Bus VT inputs are displayed along with
sequence components. In addition, several calculated values are also displayed. The AVERAGE LINE VOLTAGE displays the
calculated averages of the RMS line voltages given by: .
The AVERAGE PHASE VOLTAGE displays the calculated average of the RMS phase voltages given by:
(EQ 6.6)
The NEUTRAL VOLTAGE displays the calculated neutral RMS phasor given by: (EQ 6.7)
The POS SEQ VOLTAGE displays the calculated positive-sequence voltage RMS phasor given by:
(EQ 6.8)
The NEG SEQ VOLTAGE displays the calculated negative-sequence voltage RMS phasor given by:
(EQ 6.9)
The ZERO SEQ VOLTAGE value shows the calculated zero-sequence current RMS phasor: (EQ 6.10)
