Generator set,diesel,air cooled,20kVA **

General Description:
Diesel driven generator set, air cooled and skid mounted, with an output of 20kVA at 1500rpm

General:
A complete diesel generator set including the diesel engine, alternator, control panel, automatic starting equipment, fuel tank and all other accessories for autonomous operation

Rates Power:
20kVA, 16kW, Power factor (Cos. phi = 0.8), 400/230V, 3-phase, 50Hz at NTP (Normal Temperature and Pressure)
The use of the generator as prime or stand-by should be clearly stated by the country office when the set is requested

Engine:
Heavy duty diesel engine, with the following characteristics:
Air cooled.
Synchronous speed: up to 1500rpm.
Mechanical speed governor
Heavy duty air cartridge filter
Cartridge oil filter
External fuel filter
Residential silencer
Exhaust with suitable flexible piping.
Electric starter including batteries, leads and automatic battery charging equipment

Fuel Tank:
Fuel tank of suitable construction with capacity sufficient to run the generator set continuously for 8 hours at the rated capacity
The tank is provided with suitable piping for connecting it to the engine as well as for filling the tank
Fuel level indicator placed conveniently on the panel board

Alternator:
Synchronous and brushless
Automatic fast voltage regulator, maintaining the output within 2% under normal conditions
Screen protected
CEE Sockets: one 3 pole and one 5 pole

Panel Board:
Made of steel sheets of appropriate thickness subjected to anti-oxidizing treatment and covered with epoxy resin with suitable protection factor

The panel board comprises the following:
Automatic main circuit breaker
Change over switch with positions for: "MAINS", "OFF", "GENERATOR"
Key to start and stop the unit
Emergency stop button
Set-point for speed/governor control
Set-point for voltage control
Meters for: Volts (with selector switch to show phases to zero and phase to phase voltages), amperes (three meters or with selector switch to show current in all three phases), frequency, running hours counter
Warning system for electrical and mechanical alarms

Protection:
The generator set should be equipped with automatic shutdown equipment if fatal parameters are exceeded including low oil pressure, high engine temperature and belt failure (if applicable)

Mounting:
The engine and the alternator should be connected with a heavy-duty elastic coupling and should be mounted on a common rigid base frame with anti-vibration dampers and lifting eyes flexible for transportation
Engine, alternator, fuel tank and panel should be one integrated unit mounted on skids

Connection to ground:
The generator is supplied with connection to ground system comprising low resistance rod(s), terminals, cables, etc

Environmental conditions:
The rated power of the generator is based on the following environmental conditions:
(The country office should provide the actual local conditions to enable the calculation of de-rating that fits those local conditions)
Altitude: at 150m above sea level.
Average yearly temperature 30°C
Average 24 hours temperature 40°C
Minimum temperature -10°C
Maximum operating temperature 55°C
Dust storms are expected

Accessories:
The following accessories are supplied with the generator set:
Operation and maintenance manuals (full workshop documentation for both motor and alternator), spare parts catalogues, drawings and information concerning the foundation, erection requirements, electrical connections to load and earth, all in English
Tools kit including pipe spanners for injectors etc.
Spare parts for 2,000 hours of operation within two years (including oil and air filter cartridges and at least two full sets of v-belts and a full set of cylinder head gaskets)
A full set of replacement switches/ sensors for detection of fatal parameters (low oil pressure, high engine temperature, belt failure etc.)

Options:
The following are available as optional items
Each one can be specifically requested by the country office if needed
Automatic Mains Failure (AMF)
The generator set is mounted in a sound attenuated and weather protective canopy, to reduce the noise level down to 70 dB (A) at a distance of 7 metres
Recoil starting instead of the electric starting
Trailer mounting
Manuals in languages other than English
