Synchronous Reactance in AC Machines Formulas

Synchronous reactance Xd is defined as the ratio of open-circuit voltage for a given field current to the armature short circuit current for the same field current. And is denoted by X_s. Synchronous Reactance is usually measured using the Ohm for Electric Resistance. Note that the value of Synchronous Reactance is always positive.
