Comment
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 A current phasor and phase B current
phasor (VA-VB)
CVGAPC function will measure the current phasor internally calculated as the
vector difference between the phase B current phasor and phase C current
phasor (VB-VC)
CVGAPC function will measure the current phasor internally calculated as the
vector difference between the phase C current phasor and phase A current
phasor ( VC-VA)
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 A voltage phasor
CVGAPC function will measure the phase B voltage phasor
CVGAPC function will measure the phase C 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.
