APPLICATION

& ENGINEERING DATA

GENERATOR FEATURES

Rating deﬁnitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with

BS5514, ISO3046 and DIN6271). Prime (Unlimited Running Time): Applicable for supplying electric power in lieu of commercially purchased power. Prime power is the maximum power available at

variable load. A 10% overload capacity is available for 1 hour in 12 hours. (All ratings in accordance with BS5514, ISO3046, ISO8528 and DIN6271).

SG010 / SG015

■ Four pole, revolving ﬁeld generator, directly connected to the engine

shaft through a heavy-duty, ﬂexible disc for permanent alignment.

■ Generator meets the temperature rise standards for class "F"

insulation as deﬁned by NEMA MG1-32.6.

■ All prototype models have passed a three-phase symmetrical short

circuit test to assure system protection and reliability.

■ All prototype models are tested for motor starting ability by

measuring the instantaneous voltage dip with a waveform data

acquisition system.

■ All models utilize an advanced wire harness design for reliable

interconnection within the circuitry.

■ Magnetic circuit, including skewed stator design, provides a minimal

level of waveform distortion and an electromagnetic interference

level which meets accepted requirements for standard AM radio, TV,

and marine radio telephone applications.

■ Voltage waveform deviation, total harmonic content of the AC

waveform, and T.I.F. (Telephone Inﬂuence Factor) have been

evaluated to acceptable standards in accordance with NEMA

MG1-32.

■ Alternator is self-ventilated and drip-proof constructed.

■ Fully life-tested protective systems, including "ﬁeld circuit and

thermal overload protection" and optional main-line circuit breakers

capable of handling full output capacity.

■ System Torsional acceptability conﬁrmed during Prototype Testing.
