How Do Generators Work?

When it comes to generators – due to the sheer amount of choice available – there can be confusion when deciding on the right generator for business purposes. Is a diesel generator right, or would an LPG generator be better? How do generators work, and how do I get my generator to work for my business needs and power requirements? At Dale Power Solutions, we are generator experts, and therefore wanted to shed some light on generators to make your generator decisions a whole lot easier. And should you still be in need of any guidance or advice, please don’t hesitate to get in touch with us today on 0330 999 3000.

What Are Generators?

Electrical generators are standalone machines that provide electricity when power from the power grid is unavailable. Used to supply backup power and emergency power to businesses, facilities and homes during power outages and power failures, generators are also sometimes used as the main power source in areas where a local electrical grid is unavailable or problematic to access.

Generators don’t actually create electricity. Instead, generators convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit. Once an electrical current has been established, it is directed through copper wires to power external machines, devices, or entire electrical systems.

Some electrical generators, such as those at Hoover Dam, for example, are huge and provide large amounts of energy by transferring the power created by water turning turbines into electricity. Commercial generators, however, rely on more traditional fuel sources like diesel, gas, and propane to create mechanical power that can then be forced into a circuit to create an electrical current. The output is electricity that can be used by businesses, facilities, homes and clients of all types.

How Do Generators Work?

So how exactly do generators create energy? There are 9 key parts to a generator that play an important role in getting power to where it’s needed the most. These generator parts include:

Engine: The engine supplies energy to the generator. The power of the engine determines how much electricity a generator can provide. Similar to that of cars and other engines, your generator engine requires coolant and oil, gas or diesel to operate effectively, with regular generator maintenance required to ensure your generator maintains optimum performance levels.

Alternator: This is where the conversion from mechanical energy to electrical energy happens. Also called a “genhead”, the alternator contains both moving and stationary parts that work together to create the electromagnetic field and movement of electrons that generates electricity.

Fuel System: The fuel system makes it possible for the generator to produce the energy needed. The fuel system typically includes a fuel tank, a fuel pump, a pipe connecting the tank to the engine, and a return pipe. A fuel filter removes debris before it gets to the engine and an injector forces the fuel into the combustion chamber.

Voltage Regulator: A voltage regulator helps control the voltage of the electricity that is produced, as well as helping to convert electricity from AC to DC, if required.

Cooling and Exhaust Systems: Because generators create large amounts of heat, a cooling system is necessary to ensure that the generator doesn’t overheat. The exhaust system directs and removes the fumes from that form during this generator operation.

Battery Charger: Batteries are used to start up the generator. The battery charger is a fully automatic component that ensures the battery is ready to go when needed by supplying it with a constant low-level of voltage.

Generator Control Panel: A generator control panel commands every aspect of generator operation from start up and running speed to outputs.

Along with the main assembly frame and lubrication system, these parts ensure that generators work effectively, regardless of whether they are diesel generators, natural gas generators, propane generators, or some other type.

How To Choose The Right Generator For You?

When it comes to choosing a generator, there are considerations you should take into account before selecting the right generator. Choosing a generator includes thinking about the following:

  1. What are your power requirements?
  2. Which fuel type?
  3. Where will the generator be located?
  4. What is the voltage requirement?
  5. Who will maintain the equipment?

By answering these questions, you can gain a clearer picture of generator requirements and business needs, narrowing down the generators that are suitable for your site, business or facility. At Dale Power Solutions, our generator experts can help you answer these questions and more, and suggest a suitable generator if you so wish.

Our LPG Generators

Widely used in the automotive industry, LPG generators are fastly becoming a popular generator of choice. LPG generators are versatile, allowing fuel storage in low pressure tanks, which facilitates use in remote locations or areas where natural gas is not available.

LPG generators are also used in areas where diesel is not of sufficient quality or is liable to theft. It is also an excellent solution for protected areas where a fuel spill can become a major environmental problem. LPG is environmentally-friendly, produces far less CO2 and in general, LPG generators produce less noise as well.
