Generator Systems

1. The Importance of Generator Systems

Uninterrupted Service: Kicks in immediately during a power outage to prevent critical equipment from shutting down.

Prevention of Financial Losses: Prevents raw material waste and labor losses caused by sudden stoppages on production lines.

Safety: Ensures that elevators, fire suppression systems, and security cameras continue to operate during an outage.

Comfort: Prevents a decline in quality of life, particularly in residential projects.

2. Key Points to Consider

Correct Power Calculation (Capacity):

The most common mistake is selecting a capacity that is either too low or too high for the actual need. The generator must be powerful enough to handle the inrush currents of the devices it will power.

Site Selection and Ventilation:

Airflow: The generator requires a significant amount of fresh air while operating and must be able to exhaust hot air. Insufficient ventilation causes the engine to overheat.

Foundation: It must be mounted on a flat, sturdy concrete foundation that absorbs vibrations.

Fuel Quality and Storage:

Stale or contaminated fuel is the generator’s worst enemy; it clogs filters and shortens the engine’s lifespan.

The fuel tank’s leak-tightness and ease of refueling must be checked.

Exhaust and Sound Insulation:

Exhaust fumes are harmful to human health and must be vented away from the building’s air vents.

Sound-insulated enclosures (canopies) should be preferred to prevent noise pollution.

Regular Maintenance and Testing:

If generators remain idle for extended periods, their batteries may discharge or their oil may lose its properties.

Testing the system weekly under no-load conditions and monthly under load eliminates the risk of the generator failing to start during an actual outage.

Transfer Switch (ATS):

The transfer switch, which automatically starts the generator when the grid power fails and disconnects it when power is restored, is the “brain” of the system and must be of high quality and properly configured.
