An extensive diversity of usual calamities may cause long duration of power outages. Things such as hurricanes, tornadoes, flooding, lightning, snowstorms and blizzards may stop power for many hours or days. Even a simple blown transformer or any vehicle that ran into a service pole may knock out electric power in the whole neighborhood within one day or even two days.
Almost all people are dependent on electricity, therefore, power outage for a period of few minutes turn out to be pretty irritating. When the extent of power outage stretches further an hour, more serious problems can happen that may cause things to be damaged or get costly or dangerous. During winter season, power outage usually immobilizes your heating system at home. As the home chills, (depending on the location of your residence) it may become not fit to live in. In addition, cold pipes may cause damage amounting to thousands of dollars.
During power outage refrigerators as well as freezers stop functioning. During summer, frozen food softens and may cause a real mess. If you invested in beef business, losses might reach up to one thousand dollars or more if power failure happens for many days. If you are sick and your medical condition needs special equipment, power failure may create a situation of life or death. For example, the patient is comatose in the Intensive Care Unit (ICU), the patient may die in case there is no standby generator if ever power outage occurs.
If you reside in rural area having private well as source of water, power outage cuts off the water supply. Electrical generator is a device that converts mechanical force into electric force. The mechanical power that is converted is created from nuclear and chemical force in various kinds of fuel, or taken from sources that are renewable like the falling water or wind. Electric motors, internal-combustion engines, steam engines, gas-combustion turbines, water and wind engines are the usual means to provide the automatic power for such devices.
Generators are available in wide ranges of sizes, from very little machines having few watts of output energy to extremely big power plant equipment giving big watts of energy. The operation of power generators are based in the occurrence of electromagnetic induction when a conductor travels about the magnetic field, current is stimulated in the conductor. Generator sets are the most widespread type of emergency sources of backup power for homes and business.
The electromagnet is composed of field coils attached to iron core. Current that flows into the field loops creates the magnetic fields. This current can be taken from outside source or from the armature of the system. Regulation is attained by means of sensing the production voltage, changing it to DC and comparing the level to reference electrical energy.
