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
