Cyclic phase sequence order
For three phase rotating currents, a direct cyclic sequence is defined when the three phases are
L1, L2, L3 ordered, while an inverse cyclic sequence is defined when the three phases are L1, L3, L2
ordered.
By setting with ThyVisor, working at level 1, you can select any one of the six combinations of cycli-
cal succession of the phasor currents
.
