I am reading a paper about short circuit calculations; the author speaks of positive, negative, and zero sequences but doesn't define them. I have heard the terms before but I never truly understood them; can someone enlighten me as to what they mean? I would appreciate it. I can see that they have something to do with AC impedances.
