When many people purchase a generator, they often wonder about its power output and whether it can handle their required equipment. Hansa generators have two key power ratings: rated power and maximum power. As long as the generator's maximum power isn't surpassed, it should avoid overloading. In case of emergencies, I’d like to share some practical tips on how to deal with an overload situation.
What happens if a small generator is overloaded? The handling process depends on the specific circumstances:
(1) If the small generator is overloaded, closely monitor and control the temperature, cooling gas flow, and internal cooling water pressure and flow rates of all components. Keep detailed records to identify any anomalies and determine their root causes.
(2) Based on the degree of overload, adjust the active and reactive power of the generator to ensure that the stator and rotor currents don’t exceed their rated values.
(3) If the overload is due to a malfunctioning automatic excitation regulator, disable the faulty regulator and switch to manual mode to keep the rotor current within acceptable limits.
(4) If the system voltage and frequency drop, it might indicate a system failure causing the overload. In such cases, stop the generator immediately and address the issue.
In addition to these steps, regular maintenance and inspections are crucial to prevent overloads from occurring. It’s also important to ensure that the generator is used within its specified operating conditions to avoid unnecessary stress. Always refer to the manufacturer’s guidelines for proper usage and troubleshooting. By taking these precautions, you can extend the lifespan of your generator and avoid potential damage from overloading.
