TECHNICAL INFORMATION The generators are designed in compliance with: IEC 60034-1 ; CEI EN 60034-1 ; BS 4999-5000; VDE 0530, NF 51 -100,111 ; OVE M-10; NEMA MG 1.22; UL1446, and UL1004B is available on request. MarelliGenerators bear the "CE" mark for all generators. Vibration level in accordance to IEC 60034-14. *: medium voltage 400 + 500 Frame size 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...

Generators from frame sizes 160 to 500 for industrial application are supplied 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 a residual harmonic ^ 2%. Total Harmonic Distortion (THD) ^ 2%. TELEPHONE INTERFERENCE The Telephonic Harmonic Factor (THF) is less than 2% as defined by IEC 60034-1. RADIO INTERFERENCE Radio interference conforms to Class B Group 1 as defined by EN55011. THREE PHASE SHORT CIRCUIT CURRENT Generators with auxiliary windings or PMG ensure a three phase short-circuit...

INSULATION, IMPREGNATION AND PROTECTIVE TREATMENT OF WINDING Class H insulation system. The generators are impregnated with high grade resin, using the latest 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 DEGREE The standard protection degree is IP 23. Generators can be supplied wjth protection degree IP 55 on request. Higher protection degrees are available for frame sizes 250 to 710 through the...
