The fault
How the networks connect
In the boxes, j marks a reactance; a plain number is a resistance.
Where the current goes
Arrows (phasors)
Thick arrows are phases. Thin arrows are sequence pieces: solid = positive, dashed = negative, dotted = zero.
Which fault is worst?
All four side by side
Add them back up
Each phase is its zero, positive and negative pieces laid tip to tail. The faint wide arrow is the phase itself.
