Only values 1-3 of the parameter GlobalBaseSel should normally be
used. The values 1-3 refer to the global base value groups Phase Grp
1, Phase Grp 2 and Phase Grp 3 correspondingly (BASEPH1,
BASEPH2 and BASEPH3 in PCM600). The selection affects the
actual limit for frequency calculation set by MinValFreqMeas which
by default is 10% of the Voltage base Val PP in the selected group.
The values 4-6 refer to Residual Grp 1, Residual Grp 2 and Residual
Grp 3 (BASERES1, BASERES2 and BASERES3 in PCM600)
correspondingly and they are typically not to be used in this
connection.
