Comment
CVGAPC function will measure internally calculated negative
sequence current phasor
CVGAPC function will measure internally calculated zero sequence
current phasor multiplied by factor 3
CVGAPC function will measure current phasor of the phase with
maximum magnitude
CVGAPC function will measure current phasor of the phase with
minimum magnitude
CVGAPC function will measure magnitude of unbalance current, which
is internally calculated as the algebraic magnitude difference between
the current phasor of the phase with maximum magnitude and current
phasor of the phase with minimum magnitude. Phase angle will be set
to 0° all the time
CVGAPC function will measure the current phasor internally calculated
as the vector difference between the phase L1 current phasor and
phase L2 current phasor (I -I
L1
CVGAPC function will measure the current phasor internally calculated
as the vector difference between the phase L2 current phasor and
phase L3 current phasor (I -I

CVGAPC function will measure the current phasor internally calculated
as the vector difference between the phase L3 current phasor and
phase L1 current phasor ( I
L3
CVGAPC function will measure ph-ph current phasor with the
maximum magnitude
CVGAPC function will measure ph-ph current phasor with the
minimum magnitude
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
Comment
CVGAPC function will measure the phase L1 voltage phasor
CVGAPC function will measure the phase L2 voltage phasor
CVGAPC function will measure the phase L3 voltage phasor
CVGAPC function will measure internally calculated positive sequence
voltage phasor
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.
