Description

• Excellent reliability • All generators are equipped with an auxiliary winding excitation supply, which ensures sufficient short circuit current capability for the safe and reliable operation of the protective devices. • The generators also feature permanent magnet insertion (PMI) in the exciter machine, which together with GROWTH ENERGY’s new AVR (automatic voltage regulator) ensures easy, fast and reliable start-ups – even after long periods of storage or standby. • 2/3 winding pitch minimizes 3rd harmonic of line to neutral voltage. The generators are optimized to ensure very low levels of voltage waveform distortion. • rotor windings are made from enamelled round copper wire (G2) of thermal class **0. • Vacuum pressure impregnation (VPI) with a high quality polyester-imide resin is used in all stators, rotors and exciters. The windings can withstand all expected mechanical and electrical shocks and vibrations, as well as chemical substances. • The combination of a strong, fabricated steel frame and GROWTH ENERGY’s standard painting system makes the generators robust and durable. • In order to minimize vibration in gensets, all critical parts have been thoroughly tested using advanced FEM tools to avoid natural frequencies near the excitation bandwidths of engines. • Careful design guarantees the best mechanical safety and reliability, even when operating with high torque and output power in demanding circumstances. • Superior efficiency • Advanced ventilation design makes for highly efficient cooling. • The shorter winding overhang end design reduces copper losses and boosts overall efficiency. • High grade roundel stator silicon steel sheets, insulated on both sides, minimize shaft currents and iron losses, and also enhance the mechanical rigidity of the generators. • High quality • GROWTH ENERGY has more than *0 years of experience in the design and manufacture of generators. This expertise, applied using the most advanced tools and equipment, ensures that the LV generators meet the highest quality standards. • Ready availability • Excellent availability of both generators and spare parts • Effective *4/7 after-sales support • Easily accessible online documentation
