ACB Sequence
In the ACB sequence, the order of the voltage waveforms through time is A, C,
and B. For the AP30, the first waveform is always A and its zero crossing rising is
always 0
°
.

Phase Angles
The AP30 allows customization of phase sequence, labels, and angles to suit the
preferences of the user. The phase angles are 120
°
apart, and can be labeled
according to preference.
