1-2 The set power and voltage characteristic curves The following curves indicate generator performance at average conditions. The performance may vary according to ambient temperature. Before generator set leave the factory, voltage is set beyond rated voltage. When generator set start running, output voltage should be equal to rated output, as load time increase, rated voltage decrease.
