13 MaxPh-Ph CVGAPC function will measure ph-ph current phasor with the maximum
magnitude
14 MinPh-Ph CVGAPC function will measure ph-ph current phasor with the minimum
magnitude
15 UnbalancePh-Ph CVGAPC function will measure magnitude of unbalance current, which is
internally calculated as the algebraic magnitude difference between the
ph-ph current phasor with maximum magnitude and ph-ph current
phasor with minimum magnitude. Phase angle will be set to 0° all the
time
The user can select a voltage input, by a setting parameter VoltageInput , to measure one of
the voltage quantities shown in table 39.

1 phase1 CVGAPC function will measure the phase L1 voltage phasor
2 phase2 CVGAPC function will measure the phase L2 voltage phasor
3 phase3 CVGAPC function will measure the phase L3 voltage phasor
4 PosSeq CVGAPC function will measure internally calculated positive sequence
voltage phasor
5 -NegSeq CVGAPC function will measure internally calculated negative sequence
voltage phasor. This voltage phasor will be intentionally rotated for 180°
in order to enable easier settings for the directional feature when used.
6 -3*ZeroSeq CVGAPC function will measure internally calculated zero sequence voltage
phasor multiplied by factor 3. This voltage phasor will be intentionally
rotated for 180° in order to enable easier settings for the directional
feature when used.
7 MaxPh CVGAPC function will measure voltage phasor of the phase with
maximum magnitude
8 MinPh CVGAPC function will measure voltage phasor of the phase with
minimum magnitude
9 UnbalancePh CVGAPC function will measure magnitude of unbalance voltage, which is
internally calculated as the algebraic magnitude difference between the
voltage phasor of the phase with maximum magnitude and voltage
phasor of the phase with minimum magnitude. Phase angle will be set to
0° all the time
10 phase1 - phase2 CVGAPC function will measure the voltage phasor internally calculated as
the vector difference between the phase L1 voltage phasor and phase L2
voltage phasor (UL1-UL2)
11 phase2 - phase3 CVGAPC function will measure the voltage phasor internally calculated as
the vector difference between the phase L2 voltage phasor and phase L3
voltage phasor (UL2-UL3)
12 phase3 - phase1 CVGAPC function will measure the voltage phasor internally calculated as
the vector difference between the phase L3 voltage phasor and phase L1
voltage phasor (UL3-UL1)
13 MaxPh-Ph CVGAPC function will measure ph-ph voltage phasor with the maximum
magnitude
14 MinPh-Ph CVGAPC function will measure ph-ph voltage phasor with the minimum
magnitude
15 UnbalancePh-Ph CVGAPC function will measure magnitude of unbalance voltage, which is
internally calculated as the algebraic magnitude difference between the
ph-ph voltage phasor with maximum magnitude and ph-ph voltage
phasor with minimum magnitude. Phase angle will be set to 0° all the
time
