Application manual
Comment
CVGAPC function will measure the current phasor internally calculated as
the vector difference between the phase L3 current phasor and phase L1
current phasor ( IL3-IL1)
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
VoltageInput , to measure one of the following
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.
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.
CVGAPC function will measure voltage phasor of the phase with
