Short circuit ratio (synchronous generator)

For other uses, see Short circuit ratio (disambiguation).

In a synchronous generator,[1] the short circuit ratio is the ratio of field current required to produce rated armature voltage at the open circuit to the field current required to produce the rated armature current at short circuit.[1][2] This ratio can also be expressed as an inverse of the saturated[3] direct-axis synchronous reactance (in p.u.):[4]
