CALCULATION OF VOLT-DROP IN A CIRCUIT CONTAINING AN INDUCTION MOTOR 583

Figure G.7 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 0.8 pu standing load. The motor can have different ratios of starting current to running current.

Figure G.8 Volt-drop when starting an induction. 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
0.8 pu standing load. The motor can have different ratios of starting current to running current.
