since their generated emfs contribute to the short-circuit current. The diagram
should take induction motors into account by a generated emf in series with an
inductive reactance if the diagram is to be used to determine the current
immediately after the occurrence of a fault . In duction motors are ignored in
computing the current a few cycles after the fault occurs because the current
contributed by an induction motor dies out very quickly after the induction
motor is short-circuited .
