Transient ratingsThe voltage drop due to the application of full load at 0,8 power factor inductive on industrial 160 ÷ �00 frame size generators varies between 16% and �0% of the rated voltage: the output voltage recovers to within �% of the rated value in less than 0,� seconds.

No-Load 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.

Parallel operationAll 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.

Single phase operationThree phase (1�-wire) wound generators can be reconnected and derated to 66% for single phase operation (with a zig-zag connection).Otherwise generators with dedicated (�-wire) single phase windings can be supplied on request.

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 �-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.

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 size �00 to �50 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 ��5 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 regulationAvailable 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 protectionGenerators from frame sizes 160 to �50 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 CURRENTGenerators with auxiliary windings or PMG ensure a three phase short-circuit current (Icc) higher than � times the rated current (In): Icc > � In.Generators from 500 frame size are supplied with an over excitation device which ensures a three phase short circuit current higher than � times the rated current.
