STANDARD FEATURES
1. ENGINE
Perkins Engine Co. heavy duty
industrial EPA compliant diesel engine.
1.1 Governor
Mechanical, compliant with BS5514,
Class A1.
1.2 Electrical System
12 Volt DC. Energized to run shutdown
solenoid. Oil pressure and coolant
temperature/level shutdown switches
and gauge senders.
1.3 Derates
Genset power derates will be
required in accordance with engine
manufacturers above 86°F (30°C).
2. COOLING RADIATOR
Radiator and cooling fan complete
with protection guards, designed
to cool the engine in ambient
temperatures up to 120°F (49°C).
3. ENGINE FILTRATION SYSTEM
Cartridge type dry air filters with
restriction indicator. Racor Fuel Filter in
addition to engine filter. Cartridge type
fuel filters and full flow lube oil filters.
All filters have replaceable elements.
4. EXHAUST SYSTEM
Critical Silencer with flexible connector.
All internal pipework lagged.
5. ELECTRICAL SYSTEM
12 Volt system with battery charging
alternator, and starter motor on
engine, battery rack mounted on the
generator set baseframe and battery
charger mounted on control panel.
Battery rack will accept a variety of
battery sizes.
6. GENERATOR
Screen protected and drip-proof, self
exciting, self-regulating brushless
generator with fully interconnected
damper windings, IC06 cooling system
and sealed-for-life bearings. Switchable
voltage output.
6.1 Insulation System
The insulation system is Class H.
Windings are impregnated in a triple
dip thermo-setting moisture, oil and
acid resisting polyester varnish. Heavy
coat of anti-tracking varnish for
additional protection against moisture
or condensation.
6.2 Electrical Characteristics
Electrical design in accordance with
BS5000 Part 99, IEC60034-1,
EN61000-6, NEMA MG-1.22.
6.3 Automatic Voltage Regulator (AVR)
The fully sealed automatic voltage
regulator maintains the voltage within
the limits of ± 0.5% at steady state
from no load to full load.
Nominal adjustment is by means of
a trimmer incorporated in the AVR.
The panel door incorporates an
additional voltage adjustment
potentiometer.
6.3.1 Permanent Magnet Generator
Providing 350% short circuit
capabilities, enhanced Motor Starting
and non-linear loading performance.
6.4 Waveform Distortion,THF and TIF
Factors
The total distortion of the voltage
waveform with open circuit between
phases or phase and neutral is in the
order of 1.8. On a 3 phase balanced
harmonic-free load the total distortion
is 4%. Machines are designed to have a
THF less than 2% and a TIF less than
50. A 2/3 pitch factor is standard on all
stator windings.

to the generator rotor and a full
torsional analysis has been carried out
to guarantee no harmful vibration will
occur in the assembly.
7.3 Anti-Vibration Mounting Pads
Captive anti-vibration pads are affixed
between engine/generator feet and
the baseframe ensuring complete
vibration isolation of the rotating
assemblies and enabling the machine
to be placed on an uneven surface

with a critical engine silencer this
provides an overall noise reduction
from 65 to 68 dBA at 23 feet through
the range.
12. FACTORY TESTS
The generator set is load tested before
dispatch. All protective devices, control
functions and site load conditions are
simulated and the generator and it’s
systems checked, proved and then
passed for dispatch. A test certificate
can be provided upon request.
13. EQUIPMENT FINISH
All sheet metal components including
the enclosure and the base tank are
fully degreased, phosphated and
chromated for anti-corrosive protection
prior to painting with polyester powder.
The powder is cured at a temperature of
392°F (200°C) to ensure maximum scuff
resistance and durability. All fasteners
are electroplated. The engine and
generator are thoroughly cleaned and
finished in temperature controlled
ovens with industrial high gloss
polyurethane paint.

RATING DEFINITIONS
Standby — Applicable for supplying continuous electrical
power (at variable load) in the event of a utility power failure.
No overload is permitted on these ratings. The generator on
the generator set is peak prime rated (as defined in ISO8528-3)
at 86°F.
Prime — Applicable for supplying continuous electrical power
(at variable load) in lieu of commercially purchased power.
There is no limitation to the annual hours of operation and
the generator set can supply 10% overload power for 1 hour
in 12 hours.
