GENERATOR, EXCITER, AND VOLTAGE REGULATOR A. Comply with NEMA MG 1. B. Drive: Generator shaft shall be directly connected to engine shaft. Exciter shall be rotated integrally with generator rotor. C. Electrical Insulation: Class H. D. Stator-Winding Leads: Brought out to terminal box to permit future reconnection for other voltages if required. E. Range: Provide range of output voltage by adjusting the excitation level. F. Construction shall prevent mechanical, electrical, and thermal damage due to vibration, overspeed up to 125 percent of rating, and heat during operation at 110 percent of rated capacity. Stator shall be skewed construction to minimize harmonic voltage distortion. G. Enclosure: Drip proof. H. Instrument Transformers: Mounted within generator enclosure.
