To measure negative sequence impedance of an alternator, we short the white and blue phases, measure the current and then divide it by the voltage of the red phase. Then to measure zero sequence impedance, we short the rotor and connect the stator in open delta and inject a current.
My question is, how or why does it give us the negative and zero sequence impedance ?, I don't quite understand the method
