SECTION II. DESCRIPTION AND DATA
General. The generator set (see Figure 1-1 through Figure 1-8) Is an enclosed, diesel engine-driven, prime
utility (Type II) unit, producing 750 kW, at 60 Hertz (Hz), 625 kW at 50 Hz, 0 8 power factor (pf), lagging, with the
following output voltages:
For 60 Hz operation. 2400/4160 volts, 3 phase, 4 wire, wye (2400 volts line-to-neutral, 4160 volts line-to-
For 50 Hz operation. 2200/3800 volts, 3 phase, 4 wire, wye (2200 volts line-to-neutral, 3800 volts line-to-
Engine. The engine Is liquid-cooled, 12 cylinder, 2300 cubic inch (37 7 liters) displacement, four-stroke cycle
diesel, turbocharged, and aftercooled.
Generator. The generator is a brushless, rotating exciter, single bearing, air-cooled, open-drip-proof unit.
The generator is directly connected to the engine and delivers 50 Hz, 781 3 kVa at 0 8 power factor at 1500 revolutions
per minute (rpm) or 60 Hz, 937.5 kVa at 0 8 power factor at 1800 rpm. The generator is wye connected.
Housing. The housing is a weathertight, removable enclosure, bolted to a skid-base. Doors enable access
to major components for service or maintenance Air intake an exhaust opening allow set operation with all doors closed.
A permanently installed ladder allows access to the roof of the generator set. The roof will support a 200 pound (91 kg)
person. Fixed partitions within the housing divide the generator set Into an engine compartment, switchgear
compartments (cabinets), and weathertight control compartments (control room).
Control Room. The control room has 24 square feet (2.2 square meters) of floor space and Is equipped with
lights, exhaust fan, space heaters, and a small desk. Generator controls, on two panels, and engine controls, on a third
panel, enable operation of the generator set from the control room.
Remote Control. Module (RCM) See Figure 1-9. The remote control module (RCM) is available as an
auxiliary unit used In conjunction with the generator set. It allows remote start, stop, monitor, and control of a generator
set in single operation or in parallel operation with the like sets from a remote location of up to 100 feet (30 m) away.
Details on the operation and maintenance of the RCM are contained in Chapter 5 of this manual.
