Comment
CVGAPC function will measure the phase A current phasor
CVGAPC function will measure the phase B current phasor
CVGAPC function will measure the phase C current phasor
CVGAPC function will measure internally calculated positive
sequence current phasor
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 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
