i Series II / iX Series II / iM Series II
normally programmed phase angle relationship. For firmware upgrades, contact
.
Note that required phase angles and amplitudes are automatically set for dips of 0, 40, 70, 80
and 100% to conform with method (A). For all other dip levels, method (A) can be used by
programming the required phase angles to be used during the programmed dips. The amplitude
and phase angles required to obtain the correct line-to-line voltage dip per method (A) for
standard dip levels of 40, 70 and 80% are embedded in the firmware and conform to table C.2 of
IEC 61000-4-34.
Since all phase programming on the iX series is referenced to phase A, voltage dip with a phase
angle for A other than 0° are implemented by offsetting all three phases by the required number
of degrees to get phase A at 0°. This is reflected in the actual output settings shown on the iX
versus the data in table C.2 of the IEC61000-4-34. The actual output settings are shown in the
last 3 columns.
Phase Mapping
The phase rotation on the iX series is ACB. This means phase A is mapped to L1, phase B is
mapped to L3 and phase C is mapped to L2. The required phase selection letter combination
for the required Line-to-line dip is shown in table C.2 for reference.
