3_phase circuits

[clorhidrico]

I Have to make a "help-book" for students about 3 -phase AC circuits and I whould like to know if there is a good page on the net or a book that I can use

My favorite three phase page deals with how to detect unbalance from the supply or from a three phase motor. It also has more good information.
