In a triphasic system (any), is there a way to tell if the current is entering or leaving a phase/line/load just by the angle of the phasor of the source ?
In the following picture we can see the labels IA, IB and IC. They all point towards the load.
But we know that it's not the actual current direction
What is their actual direction when VAB=380<0, VBC=380<-120 and VCA=380<120 ?
Can I tell this by the angle ?
As can be seen by this graph, when two curves cross, two currents are leaving the load, while another one is entering. 60 degrees later, in any direction, the reverse occurs.
