See the following list of supported parameters for the 8 Series relay. Note that the
same list is also supported for the MSQI logical node. MSQI parameters are displayed
only if the relay supports sensitive ground CT.
TotPF

Hz
max = 90
min = 0
HzRte
max = 15
min = -15
PPV
max = Phase VT Ratio * 240
min = 0
PhV
max = Phase VT Ratio * 240
min = 0
A$phsA, phsB, phsC
max = (Phase CT Primary * 46)
min = 0
A$neut
max = (Ground CT Primary * 46)
min = 0
A$net

min = 0
SeqA$c1, c2 ,c3
max = (Phase CT Primary * 46)
min = 0
SeqV$c1, c2, c3
max = (Phase VT Ratio * 240)
min = 0
dbAng
angle dB = (DB percentage* 360)
