The design and construction of Cummins diesel generators focus on delivering exceptional transient response and voltage stability, which are critical for applications with high in-rush currents from electric motors or sensitive electronic loads. The engines are designed for rapid load acceptance, often capable of accepting a significant block load without excessive frequency or voltage dip. The generator's excitation system and automatic voltage regulator (AVR) work in concert to maintain voltage within a tight band, typically ±1% or better. This is vital for a water treatment plant where a 600 kVA Cummins generator must start large raw water pump motors without causing nuisance trips to the plant's motor control centers. In a large office building, the generator's stable output ensures that elevator induction motors and variable frequency drives (VFDs) for HVAC systems operate smoothly during a transfer to backup power. For a semiconductor fabrication facility, a no-break power system utilizing Cummins generators with highly responsive controls protects multi-million dollar production equipment from even the slightest power fluctuation, preventing massive financial losses from spoiled production batches. A 150 kVA Cummins generator powering a rock crushing plant handles the constant, heavy shock loads from the crusher's electric motor, its robust design and responsive governor ensuring consistent performance under such strenuous conditions. To obtain specific performance data, such as transient response curves and voltage regulation specifications, and to receive a formal quotation for a generator that meets your precise electrical load characteristics, we encourage you to contact our technical sales team for a detailed application review and pricing information.
