positive, negative and zero sequence
positive, negative and zero sequence
(OP)
I took a basic power course back in college and I work for a A/E consulting firm so we dont deal with it alot, but could someone simply tell me what each of the above mean and how this is involved in a 3 phase system.






RE: positive, negative and zero sequence
So we went from three magnitudes and 3 phase angles to 9 magnitudes and 9 phase angles, seems like it just complicates things, but in reality it is so much easier, mathematically, to work with the balanced symmetrical components than with the original arbitrary values that it worth the effort.
A balance three phase system is all positive sequence. Negative sequence and zero sequence components are the result of system imbalances, including faults. Many fault types can be distinguished simply by looking at the symmetrical components. Zero sequence is created by faults to ground.
