Measured values of phase current magnitudes and phasors are displayed here. In addition, several calculated values are
also displayed. The
AVERAGE CURRENT displays the calculated averages of the Phase A, B, and C RMS currents:
(EQ 6.1)
The NEUTRAL CURRENT value displays the calculated neutral current RMS phasor given by: (EQ 6.2)
The POS SEQ CURRENT displays the calculated positive-sequence current RMS phasor as given by:
(EQ 6.3)
The NEG SEQ CURRENT displays the calculated negative-sequence current RMS phasor as given by:
(EQ 6.4)
The ZERO SEQ CURRENT displays the calculated zero-sequence current RMS phasor: (EQ 6.5)
