rmature current(abscissa). For example, the synchronous impedance correspond-ing to 576 amperes (which is the full-load current per phase of themachine) is A^*^^ 1.99 ohms 5/6 amperes Synchronous impedance is used as a basis for the predeter-mination of the regulation of the machine, thereby… … 198 ALTERNATING-CURRENT MACHINERY much as the armature resistance is usually small. Moreover theelectromotive force required to overcome synchronous reactance isvery nearly equal to the electromotive force required to overcomesynchronous impedance.
