— Conventions
Phase rotation direction
The conventional rotation direction for the current phasors is counter-clockwise.
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.
