The Onan Generator
September 3rd, 2009
When the electrical power to a business or home fails because of an accident, storm or just outages, standby generators are set automatically to start and within a few seconds can produce electricity. With the Onan generator, the power transformation is automatic and seamless, which allows the continuation of daily routines without any interruptions. The Cummins Onan automatic transfer panel is able to monitor the voltage coming from the machine. It senses when the utility’s power falls to an unsafe or unacceptable level, at which time it signals the generator that it is time to start.
The engineers that design standby or emergency generators must know exactly what the intended use will be as there are several different considerations involved. The load factor, peak loading and typical hours per year are all ways that the generator will be used and rated. Operating a generator beyond its rating will result in shorter life and more expensive operating costs. The manufacturers warranty restrictions are also based on all of the information being completely accurate.
When you have regenerative (those that start and stop) loads such as cranes, elevators and conveyors they can rely on the power source, in this case the generator, to absorb all power during their cycle. These types of loads in the overall system can affect the size and type of Onan generator needed. In addition, planning how the loading will take place helps to ensure that the other loads are connected and are also able to absorb the regenerative power, reducing the chance of any potential problems that may arise.
Brand name generators and power systems can be very complex and effectively designing the electrical systems with multiple automatic transfer switches and multiple types of loads requires a thorough understanding of generator sizing criteria, as well as the various applicable codes. Conservatively over sizing a generator because of not clearly understanding the size requirements will not only add undo expense to a project but can also be detrimental to the reliability of the entire system. In other words, check the recommendations on the Onan portable generator, as well as any other manufacturer, for specific installation instructions.
The rugged dependability and high quality features make the Onan generator products a leading name in the industry, and that includes the marine industry. Their marine generator sets have more standard features than any other sets available. They claim the top sophisticated design and development process that applies technology to noise attenuation, vibration isolation and emissions. They are known for the quiet in “quiet diesel generators,” as well as an electronic control panel that provides extensive diagnostic capabilities, ensuring that you will have everything you need at your fingertips.
