What is the outages?

also known as power failure or power , the outages are loss of electricity in the area. Bleckat can be caused by a short circuit, an overloaded electric mains or damage caused by electric leadership on unfavorable weather, falling trees and other environmental factors. The term blackout is usually reserved for serious power outages that cover a large living area or "grid" and last anywhere from an hour to a few weeks.

Power disorders, which last only for a moment before the electricity renewal, are referred to as outages and usually caused by a failure of the power line. Power disorders that cause the lights to stir, rather than come out, are the result of a reduction in voltage and are referred to as browouts . Browbouts can cause devices such as air conditioning and CRT TVs to fight more contemporary, which potentially leads to damage to overheating.

backup systems for critical elElectric devices that ensure the implementation of public safety during outages. Air traffic management equipment and air traffic control systems use generators to automatically continue the power supply when electricity is lost. Although generators only produce energy for a limited period of time, they allow critical workers to complete what they worked on at the time of the failure without interruption. Individuals are also available backup systems for electrically driven devices in their homes, which can be damaged by sudden overvoltage of electricity that can occur during outages. Computer systems that are particularly vulnerable to hardware damage and data loss can be protected by an uninterruptible power supply (UPS) such as a backup battery.

Energy restoration after an electric outage that continued the entire energy grid can be challenging. Like a car with a dead battery requires "support" from another car, power plants require help from another station in the same energy grid, ABY The system has started again. If all other power stations are without energy, Blackstart must be launched, which includes a complex process of coordination between transmission tools and power plant.

In 2007, President George W. Bush signed a policy with the Energy Independence Act and Security for the United States to upgrade its power supply networks to an intelligent grid, which can minimize the risk of outages and reduce energy and energy consumption. On a national scale, there are power outages to Americans exceeding $ 100 billion in the US (USD), according to the Institute for Electric Research (EPRI).
