In order to determine which generator you need, you should understand a few things first. For example, how do they work? What is the difference between AC and DC power? What is dc power? Will an AC generator give you what you need? Any type of generator works by converting mechanical power into electrical power through electromagnetic induction. Electromagnetic induction occurs when an electric current passes through a shifting magnetic field, which allows mechanical energy to be converted into electrical energy.
This is the main way generators produce electricity. AC and DC power generators both use electromagnetic induction to generate electricity. However, the process they use is different. An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed, and the magnet usually moves. 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. The modern-day generator works on the principle of electromagnetic induction discovered by Michael Faraday in 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 engine is the source of the input mechanical energy to the generator. The size of the engine is directly proportional to the maximum power output the generator can supply. There are several factors that you need to keep in mind while assessing the engine of your generator. The manufacturer of the engine should be consulted to obtain full engine operation specifications and maintenance schedules. Smaller engines usually operate on gasoline while larger engines run on diesel, liquid propane, propane gas, or natural gas.
Certain engines can also operate on a dual feed of both diesel and gas in a bi-fuel operation mode. OHV engines have several advantages over other engines such as:. However, OHV-engines are also more expensive than other engines. It reduces wear and tear, and ensures durability of the engine. The CIS is not an expensive feature but it plays an important role in engine durability especially if you need to use your generator often or for long durations.
It contains an assembly of stationary and moving parts encased in a housing. The components work together to cause relative movement between the magnetic and electric fields, which in turn generates electricity. It contains a set of electrical conductors wound in coils over an iron core. The rotor generates a moving magnetic field around the stator, which induces a voltage difference between the windings of the stator. This produces the alternating current AC output of the generator.
The following are the factors that you need to keep in mind while assessing the alternator of a generator:. Plastic housings get deformed with time and cause the moving parts of the alternator to be exposed. This increases wear and tear and more importantly, is hazardous to the user. The fuel tank usually has sufficient capacity to keep the generator operational for 6 to 8 hours on an average.
For commercial applications, it may be necessary to erect and install an external fuel tank. All such installations are subject to the approval of the City Planning Division. Click the following link for further details regarding fuel tanks for generators.
Common features of the fuel system include the following: a Pipe connection from fuel tank to engine — The supply line directs fuel from the tank to the engine and the return line directs fuel from the engine to the tank.
