Generators are standby devices which can supply electricity to your home during power outages. During a power outage, it allows you to continue to operate essential appliances such as refrigerators, computers, heating and cooling systems and lighting.
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output.
It is important to understand that a generator does not actually ‘create’ electrical energy. Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit. This flow of electric charges constitutes the output electric current supplied by the generator. This mechanism can be understood by considering the generator to be analogous to a water pump, which causes the flow of water but does not actually ‘create’ the water flowing through it.
The modern-day generator works on the principle of electromagnetic induction discovered by Michael Faraday in 1831-32. Faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field. This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, thus generating electric current.
The process that generators employ involves converting mechanical energy into electric energy. This is the same process that is used, on a larger scale, to produce electricity for entire communities by your local utility provider. In essence, a spinning shaft powered by an engine is used to produce a magnetic field through a coil, which in turn produces an electromotive force.
Every power generator is not ideal in every situation. If you're using a portable generator, you'll need one that's either gas, propane or diesel-fuel powered. A propane generator can also be used as a standby generator and hook directly into a large stationary propane tank. The other type of power generator is a natural gas-powered generator. This is a standby generator that will hook directly into your natural gas lines at your business and be used as a backup in case of electric failure.
Natural gas and propane generators present some risk because of their connection to those fuel lines. Because of that, they typically have several safety features installed like automatic shutdowns in case of overheating, high oil pressure or other problems, to prevent fires and explosions.
Gasoline and diesel-powered generators are the other two types that are available in both portable generators or for use as an industrial generator. A gas generator isn't a good option as a standby generator, but a diesel-powered generator can be. Each has certain advantages and disadvantages in certain situations.
The difference between a portable and stationary diesel generator is already obvious. However, I will tell more about their differences in terms of their functions.
Portable generator, as its name says, is portable and smaller in size. Because it is smaller, it also has a lower power. This kind of generator is good for supplying power to homes and smaller business establishments.
On the other hand, a stationary generator is usually huge and is capable of providing large amount of power to establishments. It also automatically supplies power whenever a blackout comes. It is the one being used by commercial buildings such as hotels, hospitals, malls, and others.
