OTHER DIP LEVELS FOR 2 PHASE SELECTIONS.
Note that any other dip level not listed in this table will result in voltage dips
conform method (B) so both phases will dip by the actual dip percentage set.
To implement user defined three phase dips other than those listed in this table,
the IEC411 phase setting for phases A, B and C may be used to set the desired
phase angle for each dip. This setting is ignored if the dip levels is set to 80, 70
or 40 but otherwise controls the phase angle of the selected phase during the
dip.
To set the phase angle for a voltage dip, select the individual phase using the
PHASE key and use the PHASE = field in the -411 screen to set the required
phase angle. Note that this is not the start phase angle for the dip but rather
the phase offset with respect to phase A. (Requires FW 1.17 on Series I MX
units or 4.17 on Series II MX units.
