INSULATION, IMPREGNATION AND PROTECTIVE TREATMENT OF WINDING For low voltage class H. For medium and high voltage class F . Windings are impregnated with high quality materials and using the latest technologies including Vacuum Pressure Impregnation (VPI). A further protective treatment is applied , making the generators suitable for tough environmental conditions. Special degrees of protection and tropicalization are available on request. WINDINGS Generators up to frame 560 included for industrial application are constructed with 2/3 pitch winding to reduce the voltage harmonic content in applications with non-linear loads. The no-load voltage waveform is sinusoidal with Total Harmonic Distortion (THD) content less than 2%. RADIO INTERFERENCE Marelli Generators are equipped with devices in order to Class B Group 1 radio interference as defined by EN55O11. PROTECTION DEGREE The standard protection degree is IP 23. Higher protection degrees are available on request for frame sizes 250 to 800 through the application of filter, air-to-air or air-to-water heat exchanger up to IP 55. VENTILATION AND DIRECTION OF ROTATION Generators are axially self-cooled and can run in both directions of rotation. Air inlet direction is: • Frame size 160 : Radial • Frame sizes 200 and higher: Axial + radial ROTOR BALANCING Rotors are dynamically balanced with a half key applied to the shaft extension in accordance with IEC 60034-14 to vibration grade normal A in standard configuration. Generators can be supplied with special vibration levels on request. VIBRATION Vibration level is in accordance with ISO 10816. Measurement, evaluation and limits of vibration severity are in accordance with IEC 60034-14. BEARINGS AND OVER SPEED Oversized bearings. The permissible over speed is 1,5 times the rated speed (referred to 50 Hz). Sleeve bearings from 400 to 900 frame sizes are available on request. TESTING CAPABILITY Marelli Motori has a high capability test room with the possibility of testing generators in their original mounting (vertical and horizontal) and for all designed voltages (up to 15000 V) and power (up to 10 MVA). Testing can be conducted at different frequency (50 Hz or 60 Hz) through a regenerative Active Front End System. Testing is carried out in compliance with all major international standards (IEC, IEEE), customer specifications, marine/navy rules.
OPERATING CONDITIONS Overloads During continuous duty (S1), the following overloads are allowed : 10% for 1 hour 15% for 10 minutes 30% for 4 minutes 50% for 2 minutes These overloads must be occasional and followed by one hour of running at normal load or less. Stand-by ratings are based on continuous supply of loads for any utility power failure. No overloads are allowed in stand-by duty. Single phase operation Three phase (12-wire) wound generators can be reconnected and derated 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. The following derating factors must be applied to the corresponding configurations Connection K factor (L - L) K factor (L - N)

Parallel operation All generators are provided with a amply sized damper cage and are suitable for parallel operation with other generators, when equipped with the paralleling unit. A power factor regulator is available on request. No-Load operation at reduced speed All regulators work to reduce the excitation current in order to protect the excitation system when the generator is being used at reduced speed. Transient ratings The 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% and 20% of the rated voltage: the output voltage recovers to within 3% of the rated value in less than 0,3 seconds. Altitude The rated outputs refer to installation up to 1.000 m a.s.l. Above this level the following derating factors must be applied. Altitude (m asl)

EXCITATION SYSTEM The 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 winding The excitation system of generators from frame size 200 to 450 is fed by an auxiliary winding which gives a better response to the variation in loads and sustains the power supply in the case of a short-circuit. Auxiliary winding on the 160 frame is available on request. Permanent Magnet Generators (PMG) The generators from frame size 225 mm and larger 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 regulation Available within ±5% of the rated value by means of a potentiometer placed inside the voltage regulator. A remote voltage setting is possible by means of an external potentiometer, which can be supplied on request. Over-excitation protection Generators from frame sizes 160 to 450 are equipped with adjustable over-excitation protection which will protect the alternator in the event of over excitation when combined with an external protection system. THREE PHASE SHORT CIRCUIT CURRENT Generators 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 frame size are supplied with an over excitation device which ensures a three phase short circuit current higher than 3 times the rated current.

Analogue AVR (MARK and MGC series) The voltage regulators are the standard features for synchronous generators of MarelliMotori. These regulators are suitable for low and medium voltage machines. The regulators are fully insulated in order to maintain high reliability also with severe ambient conditions (high level of humidity, dust, salt atmosphere), and in case of high vibrations level. The regulators can work both for single and 3-phase operations. Digital AVR (MEC100 series) MEC100 series regulators are microprocessor-based devices for the excitation control of MarelliMotori synchronous generators. The full-function and full-protection control system ensures high performances with suitable accuracy in a wide range of applications. A proprietary user-friendly software is provided with the equipment for commissioning and monitoring purposes. The MEC100 series includes models with embedded optional features like the Diode Monitoring functions. The MEC100 complies also with the DNV rules. Other AVRs may be installed on request.
