2.3 Engine
The diesel engine which powers the generator is specifically designed for power
generation. It has high reliability. The engine is of the heavy duty industrial type with 4
stroke compression ignition and is fitted with all accessories to provide a reliable
power supply. These accessories include, among others, a cartridge type dry air filter
and a mechanical or an electronic engine speed governor. The engine uses forced
lubrication via gear pump and special paper cartridge type filters. The lubricant
cooling is generally via heat exchanger.
2.4 Alternator
The alternators are of brushless rotating field design and utilize three-phase
full-wave excitation and regulation. They are self-excited with excitation power derived
from the main output windings. They are also available with specific windings and a
transformer controlled excitation system. The alternators have four poles and twelve
lead configurations. The alternators can produce either 50Hz or 60Hz electrical power
under normal working conditions. The alternators use Wye Configurations. Figure 2-4
is voltage configuration which illustrates the proper connection and lead identification.
The leads are numbered clockwise from top and from the outside inward.
2.5 Radiator
The engine cooling system is water cooled. The water cooled system is
composed of a radiator, a fan and a thermostat. The generator has its own internal fan
to cool the generator components.
2.6 Base Fuel Tank
The engine and alternator are coupled together, and mounted on the base frame
with vibration isolators. The base frame includes a capacity of 8, 12 or 24 hours base
fuel tank. The base fuel tank is equipped with a filling cover and a fuel level gauge. It
also is connected to the engine inlet pipe and overflow pipe with hoses.
