EXCITATION SYSTEMThe generators are self-exciting, by means of a brushless type excitation system.The voltage is maintained within ± 0,5% of the nominal value in steady state condition with a balanced and non distorting load.

Auxiliary windingThe excitation system of generators from frame sizes 200 to 450 are fed by an auxiliary winding which gives a better response to the variation in loadsand sustains the power supply in the case of a short-circuit . Auxi l iary winding on the 160 frame is avai lable on request.

Permanent Magnet Generators (PMG)All generators can be supplied with a Permanent Magnet Generator (PMG) if required, which gives an independent supply to the excitation system.PMG is advisable for use with generators in particular applications such as unbalanced loads and distorting loads.

Manual voltage regulationAvailable within ± 5% of the rated value by means of a potentiometer placed inside the voltage regulator. A remote voltage setting is possible by meansof an external potentiometer, which can be supplied on request.

Over-excitation protectionGenerators from frame sizes 160 to 450 are supplied with adjustable over-excitation protection which will protect the alternator in the event of over-excitation when combined with an external protection system.

VOLTAGE AND FREQUENCYThe generators can operate at 50 and 60 Hz.

WINDINGSGenerators from frame sizes 160 to 500 for industrial application are supplied with 2/3 pitch winding to reduce the voltage harmonic content in applicationswith non-linear Ioads. The no-Ioad voltage waveform is sinusoidal with a residual harmonic 2%. Total Harmonic Distortion (THD) 2%.

TELEPHONE INTERFERENCEThe Telephonic Harmonic Factor (THF) is Iess than 2% as defined by IEC 60034-1.

RADIO INTERFERENCERadio interference conforms to Class B Group 1 as defined by EN55O11.

THREE PHASE SHORT CIRCUIT CURRENTGenerators with auxiliary windings or PMG ensure a three phase short-circuit current (Icc) higher than 3 times the rated current (In): Icc > 3 In.Generators from 500 to 800 frame size are supplied with an overexcitation device VARICOMP which ensures a three phase short circuit current higherthan 3 times the rated current.

OVERLOADSThe following overloads are allowed (only for continuous duty): 10% for 1 hour, 15% for 10 minutes, 30% for 4 minutes, 50% for 2 minutes.These overloads must be occasional and followed by at Ieast one hour of running at nominal Ioad or Iess.

OPERATING CONDITIONS

Single phase operationThree phase (12-wire) wound generators can be reconnected and de-rated to 66% for single phase operation (with a zig-zag connection).Otherwise generators with dedicated (4-wire) single phase windings can be supplied on request.

Parallel operationAll generators are provided with a largely sized damper cage and are suitable for parallel operation with other generators, when equipped with theparalleling unit. A power factor regulator is available on request.

No-Ioad operation at reduced speedAll regulators work to reduce the excitation current in order to protect the excitation system when the generator is being used at reduced speed.

Transient ratingsThe voltage drop due to the application of full load at 0,8 power factor inductive on industrial 160 - 400 frame size generators varies between 16 and20% of the rated voltage: the output voltage recovers to within 3% of the rated value in less than 0,3 seconds.

AltitudeThe rated outputs refer to installation up to 1.000 m a.s.l.Above this level the following derating factors must be applied.

INSULATION, IMPREGNATION AND PROTECTIVE TREATMENT OF WINDINGClass H insulation system (Class F insulation for M.V. and H.V.). The generators are impregnated with high grade resin, using the Iatest technologies(VPI).A further protective treatment is applied on the whole range, making the generators suitable for tough environmental conditions.Special degrees of protection and tropicalisation are available on request.

PROTECTION DEGREEThe standard protection degree is IP 23. Generators can be supplied with protection degree IP 55 on request.Higher protection degrees are available for frame sizes 250 to 800 through the application of air-to-air or air-to-water heat exchangers.

VENTILATION AND DIRECTION OF ROTATIONGenerators are axially self-cooled and can run in both directions of rotation.Air inlet is:• Radial - Frame size 160.• Advanced axial + radial - Frame sizes 200 ÷ 355.• AxiaI + radial - Frame radial sizes 400 ÷ 800.

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) instandard configuration. Generators can be supplied with reduced (R) or special (S) vibration Ievels on request.

BEARINGS AND OVERSPEEDGenerously oversized roller bearings. The permissible overspeed is 1,5 times the rated speed (referred to 50 Hz).Sleeve bearings from 400 to 800 frame sizes are available on request.
