How Generators Work Electrical generators are standalone machines that provide electricity when power from the local grid is unavailable.
Generators are often used to supply backup power to facilities, businesses, or homes during power outages but they can also be used as a primary power source in areas where a local electrical grid is unavailable or difficult to access such as mining and farming operations or even new developments and construction.
It’s possible to buy a generator for just about any need. Some electrical generators are small, portable devices that are used for camping or hobbies to provide small amounts of power for just a few devices.
Others are permanent installations that can power an entire house. Industrial generators are even more powerful, capable of maintaining full power to manufacturing facilities, hospitals, and office complexes.
There are diesel generators, natural gas generators, propane generators, and bi-fuel generators. Below, we’ll take a look at how electrical generators work and what you need to know to install and maintain a generator.
