STANDARDSAll generators are designed according to the IEC 60034-1, CEI EN 60034-1, BS 4999-5000, VDE 0530, NF 51-100, OVE M-10 and NEMA MG 1.22 standardsand can be incorporated in the “CE” marked machinery.

AVAILABLE VOLTAGEGenerators can be supplied with the following voltage range:• Low voltage (380 - 480 V)• Medium voltage (3.000 - 6.600 V)Voltages not listed can be supplied on request.

EXCITATION SYSTEMGenerators are self-excited through a brushless type excitation system.The voltage is maintained within ± 0,5% of the nominal value in steady state conditions.Generators are equipped with an auxiliary winding, or with the Varicomp overexcitement device, in order to supply a three-phase short circuit current 2,5 timesgreater than the nominal current of the generator.

OVERLOADSThe following overloads are permitted: 10% for one hour, 15% for ten minutes, 30% for four minutes and 50% for two minutes. All overloads must occuroccasionally and must be followed by a minimum of one hour of running at nominal load or less.

OPERATING CONDITIONS

Parallel operationAll generators are provided with an oversized damper cage and are suitable for parallel operation with other generators, when equipped with a paralleling unit.An automatic power factor regulator is available on request.

Environmental conditionsThe rated outputs refer to an installation height up to 1.000 m asl and to a maximum ambient temperature of 40°C. For higher altitudes and different temperaturevalues the rated outputs must be re-calculated using the factors listed in the following table.


For negative power factors please contact MarelliMotori.

DEGREE OF PROTECTIONStandard generators are air-cooled with an IP 23 degree of protection (IC 01 cooling type). Inlet and outlet air filters (IC 01 cooling type) are available on requestto upgrade the index to IP 44.To obtain a higher index of protection (IP 44, IP 54) generators can be supplied with an air-to-water heat exchanger installed on the body of the machinery (IC81W cooling type).

SHAFT ORIENTATIONGenerators are supplied with a horizontal (IM B3) or vertical (IM V10) shaft configuration. The vertical generators are equipped with a thrust bearing on the no-drive-end (NDE) side.

BEARINGSStandard generators are supplied with grease-lubricated rolling bearings. All bearings are oversized to guarantee a minimum lifetime of 100.000 h (L10h = 100.000h), value obtained concerning to an unloaded standard shaft. The NDE bearing is conveniently insulated (*) to avoid shaft currents.

RUNNER DIRECTLY CONNECTED TO THE SHAFTGenerators can be equipped with a special shaft extension to directly connect the hydraulic turbine runner. In this configuration all bearings and the shaft aredesigned to withstand to axial and radial loads caused by the hydraulic thrust and by the weight of the runner. Depending on the loads applied and on the runawayspeed of the runner, generators can be supplied with oil-lubricated rolling bearings or sleeve bearings.

ROTOR BALANCINGRotors are dynamically balanced with a half key applied to the shaft extension in accordance with IEC 60034-14 to vibration grade normal (N) in standardexecution. Generators can be supplied with reduced (R) or special (S) vibration levels on request.

Power factorThe nominal power factor is 0,8 lagging. For different power factor values the following derating factors must be applied:

INSULATIONClass H standard insulation system allows a maximum winding temperature rise of 125°C referring to an ambient temperature of 40°C. Windings are impregnatedwith polyester resin using the latest technology (VPI system). An enamel insulator (tropicalization treatment) coats all inner parts of the generator in order toprotect it from corrosion.

TEMPERATURE SENSORSGenerators are equipped with three PT100 temperature sensors (one for each phase) installed into the slots to supervise the stator winding temperature andwith a PT100 for each bearing to monitor its temperature (**). To control inlet and outlet air temperature of the air-to-water heat exchanger, PT100’s are installedboth on the NDE side and on the drive-end (DE) side on request. If the air-to-water heat exchanger is installed, PT100’s are used to control the inlet and outletwater temperature.

FLYWHEELWhen the requested inertial momentum is higher than the actual inertial momentum of the generator, it is possible to extend the shaft on the NDE side in orderto connect a flywheel.

TERMINAL BOXESGenerators are supplied with terminal boxes of appropriate dimensions in order to allow easy connection to the main leads. All generators allow the connectionto the main leads and to the star point.Two different terminal boxes, one for the star point and one for the leads for the auxiliary devices, are available on request.Generators can be equipped with current transformers both on the main leads and the star point leads.The standard degree of protection for terminal boxes is IP 44; the IP 55 can be installed on request.

SYNCHRONOUS GENERATORS / OVERALL DIMENSIONS [mm]

STANDARDSAll generators are designed according to the IEC 60034-1 and CEI EN 60034-1 standards and can be incorporated in the “CE” marked machinery.

AVAILABLE VOLTAGEGenerators can be supplied with nominal voltages from 380 V up to 690 V.Voltages not listed can be supplied on request.

ENVIRONMENTAL CONDITIONSRated outputs refer to an installation height up to 1.000 m asl and to a maximum ambient temperature of 40°C. For higher altitudes and different temperaturevalues the rated outputs must be recalculated using the factors listed in the following table.


DEGREE OF PROTECTIONStandard generators are air-cooled with an IP 23 degree of protection (IC 01 cooling type). To upgrade the index to IP 44 inlet and outlet air protections areavailable on request (IC 01 cooling type).To obtain a higher degree of protection (IP 44 or IP 54), generators can be supplied with an air-to-fresh water heat exchanger installed on the body of the machinery(IC 81W cooling type).

SHAFT ORIENTATIONGenerators are supplied with a horizontal (IM B3) or vertical (IM V10) shaft configuration.

BEARINGSStandard generators are supplied with grease-lubricated rolling bearings. All bearings are oversized to guarantee a minimum lifetime of 100.000 h (L10h = 100.000h), value obtained concerning to an unloaded standard shaft.

RUNNER DIRECTLY CONNECTED TO THE SHAFTGenerators can be equipped with a special shaft extension to directly connect the hydraulic turbine runner. In this configuration all bearings and the shaft aredesigned to withstand to axial and radial loads caused by the hydraulic thrust and by the weight of the runner. Depending on the loads applied and on the runawayspeed of the runner, generators can be supplied with oil-lubricated rolling bearings or sleeve bearings.

ROTOR BALANCINGRotors are dynamically balanced with a half key applied to the shaft extension in accordance with IEC 60034-14 to vibration grade normal (N) in standardexecution. Generators can be supplied with reduced (R) or special (S) vibration levels on request.

INSULATIONClass F standard insulation system allows a maximum winding temperature rise of 105°C referring to an ambient temperature of 40°C. The windings areimpregnated with polyester resin using the latest technology (VPI system). An enamel insulator (tropicalization treatment) coats all inner parts of generators inorder to protect it from corrosion.

TEMPERATURE SENSORSGenerators are equipped with three PTC thermistors (one for each phase) to supervise the stator winding temperature. Generators can be supplied with a PT100for each bearing in order to control their temperature. To control inlet and outlet air temperature, PT100’s are installed both on the NDE side and on the DE sideon request. If the air-to-water heat exchanger is installed, it’s possible to control the inlet and outlet water temperature by PT100’s and to install a flow meterto check presence or absence of water.

FLYWHEELWhen the requested inertial momentum is higher than the actual inertial momentum of the generator, it is possible to extend the shaft on the NDE side in orderto connect a flywheel (not supplied).

TERMINAL BOXESGenerators are supplied with terminal boxes of appropriate dimensions in order to allow easy connection to the main leads. All the generators have six leads inthe terminal box.An additional terminal box for the leads of the auxiliary devices is available on request.Generators can be equipped with current transformers both on the main leads and the star point leads.The standard index of protection for the terminal boxes is IP 55; the IP 56 can be installed on request.
