How Does a Generator Work?

A generator is a device capable of generating electrical energy. Energy is an essential resource that millions of people depend on to get to work, complete common everyday tasks, and keep vital equipment operating. When a power outage occurs, electrical power grids can fail. Generators are used as a back-up source of power, and they minimize electrical faults.

How Does it Work?

Most generators are known as a direct current generator, and it’s dependent on the electromagnetic induction which is capable of converting or transforming it into electrical energy. One of the most popular types of energy generators is called the dynamo. It uses the existing mechanical energy and converts it into the shaft’s rotation. This causes the strength of the magnetic field to oscillate, and voltage induction is created at its terminals. When these components are subjected to loads, it produces the circulation of energy.

Different Types of Generators

There are different types of generators available in a variety of models; therefore, they produce different types of power, and it’s best to choose one that meets your specific need. It’s also important to understand that electric motors are just like generators. They can convert electrical power into mechanical power; however, there is also chemical energy that can be converted into electrical power through the use of batteries, natural gas, and propane.

You may have heard of photovoltaic generators? They’re used in homes or businesses that utilize solar panels, this type of generator converts solar power into electricity.

The most common types of generators are:

  • Continuous current generators
  • Synchronous generators
  • Asynchronous generators


Where Are They Used?

Power generators are typically found in hospitals, large industries, hotels, government facilities, and some houses. Power generators are vital to these establishments because they’re needed for life support systems, computer programs that run intricate machinery, security systems, and other vital components that can never go without power. You can usually see them mounted on flat roofs or in a heavy-duty wire cage somewhere on the property. They look like a big diesel engine on steroids, and they are a serious piece of machinery with a very expensive price tag.

Portable Generators for Emergency Backup Power

Gas-powered portable generators are the most common type of generator for emergency backups. They work by converting mechanical energy into electrical power that you can use in your house when there’s a power outage. Due to the emissions that a gas-powered generator produces, they are usually kept outside of the house because of the risk of carbon dioxide poisoning.

They can be hard-wired into your breaker box by a licensed electrician or extension cords can be plugged into them and used to power vital household components like refrigerators, water pumps, hot water tanks, and heating/AC systems. They’re also a lifesaver for keeping cell phones charged during a storm and running electrical appliances like computers and televisions as well as having sufficient lighting during the nighttime hours.

Can Generators Work in Remote Locations?

Generators can work in remote locations where there’s no electrical service. The most common type of generator for remote locations is the petroleum gas-powered generator. These are perfect for those who need electrical power in hunting lodges, camps or even ice shacks. Depending on the use, a generator with less or more watts is determined by the amount of electrical power draw.

For example, if you’re using it to run a hunting camp for the weekend? A 2000W generator will work just fine, however, if you’re using one in a remote location to power a small home on a regular basis, you should consider getting a gas-powered generator that has 7500W or more. Another solution as mentioned above is to install solar panels. Solar panels in remote locations are a great way to harness the sun’s energy, and photovoltaic generators can power the home, eliminating the need to lug gasoline.

Choosing a Generator

Now that you know how a generator works, it’s always a good idea to choose a generator based on your need and budget. A good way to see how dependable a generator is to read customer reviews on the brands you’re researching. A company can pitch how well their generator works, but when it comes to longevity and price? Consumers who use and depend on them on a regular basis are the ones who really know how good it works.
