Portable Generators with Diesel, Gasoline, Natural Gas and Propane Power
Whenever miners of old needed light, they found ways of getting it. The source could be a tallow candle, a gas lamp or a helmet-mounted carbide lamp. But there were drawbacks to using these. If there were flammable pockets of gas in the mines, using these could result in an explosion and injury or death. The development of an electric light was a welcome development because it meant light without the fear of igniting combustible gases.
Typical Portable Generators
But these lights had to be powered somehow. Some of the first electrical generators were used to provide lighting and power equipment in mines and collieries. They were large and very heavy, and once the mine had yielded all its ore, they were useless.
Today’s advanced technology has made portable generators a reality. They are meant to be moved from place to place, so they are made to be mobile, usually mounted on a trailer or cart of some sort. Most of them can provide power for a few hours. A typical small genset can provide up to 20 kilowatts of electrical power, while trailer-mounted generators can provide a million watts. They have many uses - providing power to machines at a construction site; powering portable lighting systems, PA sets, pumps, and radio transmitters; and providing electricity in remote locations such as campsites and farms are just some of the applications they can be used for. They can also provide power to maintain communications and provide lighting, heat and refrigeration during emergencies.
Usefulness of Portable Generators
The utility of a portable power source is well-known by those who, having endured the inconvenience of power stoppages, purchased a portable generator in order to act as a standby generator, as a backup source of power in emergencies. The rolling blackouts of California and the widespread blackout of August 2003, the biggest in US history, showed how vulnerable interconnected and deregulated electric grids are to disruptions caused by something as small as a faulty circuit breaker or a fallen tree, hence, the increasing number of people who have bought portable engine generators for use in their homes.
The smaller generator models are usually gasoline generators. Larger ones can be diesel generators, natural gas generators or propane generators. A portable generator should be bought with the availability, convenience and price of these fuels in mind as well as the loads that they will bear in operation and the noise they will cause. Most portable generator sets provide single-phase electrical power. They might require the use of an external power conditioner to safely operate sensitive electronic equipment, such as computers, televisions, ballasted lights, and so on.
