CVGAPC function will measure internally calculated negative
sequence current phasor
6
3 · ZeroSeq
CVGAPC function will measure internally calculated zero sequence
current phasor multiplied by factor 3
7
MaxPh
CVGAPC function will measure current phasor of the phase with
maximum magnitude
8
MinPh
CVGAPC function will measure current phasor of the phase with
minimum magnitude
9
UnbalancePh
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
10
PhaseA-PhaseB
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)
11
PhaseB-PhaseC
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)
12
PhaseC-PhaseA
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)
13
MaxPh-Ph
CVGAPC function will measure ph-ph current phasor with the
maximum magnitude
14
MinPh-Ph
CVGAPC function will measure ph-ph current phasor with the
minimum magnitude
15
UnbalancePh-Ph
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
