Figure G.5 Volt-drop when starting an induction motor. Nomograph for the volt-drop in per-unit versus the
ratio of the motor kVA rating to the generation kVA capacity, for a generator transient impedanceZgof 0.2 pu
and zero standing load. The motor can have different ratios of starting current to running current.


Figure G.6 Volt-drop when starting an induction motor. Nomograph for the volt-drop in per-unit versus the
ratio of the motor kVA rating to the generation kVA capacity, for a generator transient impedanceZgof 0.3 pu
and zero standing load. The motor can have different ratios of starting current to running current.
