A generator is used when a power supply is needed for the whole building at the time of crisis. It is very helpful in home, work sites and other places where there is a problem in the power access e.g. a construction site or a mining factory. At such places the power cut off even for small amount of time causes great loses.
A diesel generator is normally used for a continuous power supply within the presence of fewer moving components it requires less repairing and maintenance. A diesel generator can produce continuous electricity flow without any spikes and sags. Spikes and sags can damage any device and diesel generator minimizes it in an electricity flow. Also it helps to regulate the fluctuation. In a diesel generator parts like ignition systems are absent so just with the timely and regular maintenance it can function accurately. In a diesel generator ignition system is not present due to which there are less chances of it getting spoiled. So with making them work at a high capacity can give out the most effective work function. Using them for low capacity task can start building of carbon and internal glazing. If this continues for longer time the generator starts degrading itself.
To function it properly a generator should be used at 70% of load. For short power loads UPS are most effective. Generator works by the principle of converting alternate current in to the usable current. This device is most helpful at the hospital as power cut even for few minutes can cause serious problems to many patients. The company providing the generator should do a proper testing of it before the supply to avoid any kind of problems. The service, maintenance and repairing of any kind of generator should be provided by hat company.
