Have you ever wondered how a portable generator works? Electricity generation is the process of converting any particular form of energy into electricity. Portable generators are handy appliances that provide electricity during power outages in urban and remote areas. They produce electricity by running gas-powered engines.
Portable generators can be used in areas that have no electricity, face constant power cuts, or when the power needs are minimal. Nowadays, many people find them very useful, and home-makers generally benefit from using them. This is because of the great convenience offered by these types of generators; they can easily be moved around any part of the house. They can also be beneficial for individuals in different workplaces, like the contractors and campers. So, how does the portable generator work?
A Portable Generator – How it Works
A typical portable generator contains several components assembled together into a single unit. The components include;
This type of generator comes with a small internal combustion engine. This engine operates just like any other small engine, and is powered by different types of fuels, including diesel, gasoline, propane and natural gas. However, diesel is generally preferred for generators because of its ability to burn without exploding. First, the fuel tank is filled and then the engine is started, with a key or an automatic starter.
The alternator converts mechanical energy, produced by the engine, into electrical current. It comprises of two parts; the stator and the rotor (armature). The stator is one solid iron core that contains a set of metal coils that conduct electricity. An armature or a rotor, which is powered by the small engine, spins around this stator to produce the charging magnetic field. The rotors in small portable generators, usually have permanent magnets.
The rotor runs at high revolutions per minute. The high speed rotation causes an electric current to be produced, which is then available for use by any equipment that is plugged in to the generator.
A throttle and governor are used to control the speed of the engine in order to standardize the power output of the generator while still preventing damage of components that could be caused by the engine operating at a very high speed. Basically, it makes sure the generator produces just the right and necessary amount of power, thus reducing the noise of the engine and making it more fuel efficient.
Cooling exhaust system
The temperature of the generator components must be regulated to prevent overheating during use. The generator can use a fan, a coolant or both, to control the temperature of the generator at work.
The amount of power produced by a generator depends on a wattage. The larger the wattage, the more equipment it keeps running. Portable generators come in different sizes, ranging from as small as 500 watts that can be used for camping, to as big as 17,000 watts and above that can run a small office or an entire household. The smaller ones are easier to move around, while the larger models comes with wheel kits that make them just as portable.
