Transmission and distribution refers to the different stages of carrying electricity over poles and wires from generators to a home or a business. The primary distinction between the two is the voltage level at which electricity moves in each stage. After electricity has been generated, a system of electrical wires carries the electricity from the source of generation to our homes and businesses.

Electric Power System – Generation, Transmission & Distribution of Electricity

There are three stages of electric power supply; generation, transmission and distribution. Each of these stages involves distinct production processes, work activities and hazards. Most electricity is generated at 13, to 24, volts. The hazards of the electrical power generation process include explosions and burns resulting from unexpected equipment failure. These procedures are in place to control energy sources.

Smaller power systems are also found in industry, hospitals, commercial buildings, and homes. Generation of electrical power is a process whereby energy is transformed into an electrical form. There are several different transformation processes, among which are chemical, photo-voltaic, and electromechanical. Of these, all except the wind energy conversion process take advantage of the synchronous AC generator coupled to a steam, gas or hydro turbine such that the turbine converts steam, gas, or water flow into rotational energy, and the synchronous generator then converts the rotational energy of the turbine into electrical energy. It is the turbine-generator conversion process that is by far most economical and consequently most common in the industry today.

Electric power distribution is the final stage in the delivery of electric power ; it carries electricity from the transmission system to individual consumers. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through secondary distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level.

The purpose of the electric transmission system is the interconnection of the electric energy producing power plants or generating stations with the loads. A three-phase AC system is used for most transmission lines. The operating frequency is 60 Hz in the U.

Electric Power Generation, Transmission, and Distribution

An electric power system or electric grid is known as a large network of power generating plants which connected to the consumer loads. Electrical energy is a form of energy where we transfer this energy in the form of flow of electron. So, electrical energy is obtained by converting various other forms of energy. Historically, we have done it from chemical energy using cells or batteries. However, as the invention of generator had occurred, it became the technique to first convert some form of energy into mechanical form of energy and then converting it into electrical form of energy using generator.

Бринкерхофф пожал плечами и подошел к окну. - Электроснабжение уже наверняка восстановили.  - Он открыл жалюзи. - Все еще темно? - спросила Мидж. Но Бринкерхофф не ответил, лишившись дара речи.

Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость. Только его собственные утверждения в электронных посланиях. И конечно… ТРАНСТЕКСТ. Компьютер висел уже почти двадцать часов. Она, разумеется, знала, что были и другие программы, над которыми он работал так долго, программы, создать которые было куда легче, чем нераскрываемый алгоритм. Вирусы. Холод пронзил все ее тело.

Ее завораживала глубина его темно-зеленых глаз, и она не могла отвести от них взгляд. В этот момент где-то вдали раздался оглушительный колокольный звон. Она потянулась к Дэвиду, но он исчез, и ее руки сомкнулись в пустоте. Телефонный звонок окончательно прогнал сон. Сьюзан Флетчер вздохнула, села в кровати и потянулась к трубке.

У него закружилась голова. Увидев выгравированные знаки, Беккер страшно удивился. Он совсем забыл про кольцо на пальце, забыл, для чего приехал в Севилью. Он посмотрел на приближающуюся фигуру, затем перевел взгляд на кольцо. Из-за чего погибла Меган.

Да и краска вонючая. Беккер посмотрел внимательнее. В свете ламп дневного света он сумел разглядеть под красноватой припухлостью смутные следы каких-то слов, нацарапанных на ее руке. - Но глаза… твои глаза, - сказал Беккер, чувствуя себя круглым дураком.

 Ну, если вы имеете в виду и диагностику, то времени уходило. - Насколько. Сьюзан не понимала, к чему клонит Стратмор.
