PATH: ACTUAL VALUES  A1 METERING  CURRENT
•A, B, C CURRENT: Displays the current in each phase corresponding to the A, B, and C 
phase inputs. Current will be measured correctly only if the 
CT PRIMARY is entered to 
match the installed CT primary and the CT secondary is wired to match the 1 or 5 A 
input . If the displayed current does not match the actual current , check this setpoint 
and...

•NEUTRAL CURRENT: Neutral current can be determined by two methods. One method 
measures the current via the neutral CT input . The second calculates the neutral 
current based on the three phase currents; using the instantaneous samples, 
Ia + Ib + 
Ic = In. If the sum of the phase currents does not equal 0, the result is the neutral 
current . When using the CT input , the neutral current reading will be correct only if the 
CT is...

•Van, Vbn, Vcn: Displays phase voltages corresponding to the A, B, and C voltage 
inputs. This voltage will be measured correctly only if the 
VT RATIO, VT NOMINAL

•Va PHASOR: Displays a phasor representation for the magnitude and angle of Va. Va is 
used as a reference for all other phasor angles. If there is no voltage present at the 
PQMII voltage inputs, then Ia will be used as the reference for all other angles. Va is 
also used as the reference when in Simulation Mode.
