A Brief Description Of Generators

By Misty Tyler


When there is an interruption in service from the utility company, or when the homeowner or business owner lives off the grid, there is a need for a backup power or alternative power source. Backup power means the business is able to continue caring for customers, even when there is a power failure. Here are some facts about the various types of generators Middlesex residents can utilize for alternative forms of power.

The reasons for owning a generator are varied and numerous. The generator may be a backup power source, or one which provides standby power. Other generators are the primary power source for the business or residence. Still others are the only source of electrical power. Most people do not think about their dependence upon electricity and electrical power until it is lost due to a storm, line breakages or excessive demands on the system.

The basic operating principle of a generator is based on transforming mechanical energy into electrical energy. Rather than creating energy, the power equipment transforms energy. The process is accomplished by using a magnet to move electrical particles through the wire in the windings.

Portable generators are suitable to provide power to domestic appliances when the power fails. Alternatively, they can be used at construction sites with no external power source. They operate such tools as saws, paint sprayers and drills. Construction site demands usually require power units which produce a minimum of four kilowatts of power.

The fuel source for generators can be gasoline or diesel. Some operate with natural gas. A solar unit can also be used in some instances. Deciding the right style and size will depend upon the needs of the owners and the environment where the equipment is operating.

The list of components in an electric generator includes the engine, fuel system and alternator. In addition, the unit requires cooling and exhaust capability and a lubrication system. The battery charger, control panel and frame complete the major parts, each of which is critical for producing electricity.

Connecting the alternative power source to use as backup can be done in two ways. You can use an extension cord from the generator to any appliances which need to be operated while the power is down. A safer method is to install a switch to transfer the power source at the home or business power panel. The switching can be done manually or by using a remote device. When there is an interruption in power from the utility company, the owner simply switches to the alternative power source.

If there are disadvantages to the operation of the alternative power source, they are offset by the advantages. The major complaint appear to be the noise of the engine. This can be partially offset by the housing of the device and the amount of soundproofing. Paying attention to safe operation guidelines is critical. Exhaust from a gasoline or diesel generator should not be vented indoors. Local governmental regulations may apply to the use of the equipment and its style.
