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.

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. It refers to the part of electricity delivery that moves bulk electricity from the generation sites over long distances to substations closer to areas of demand for electricity. Transmission lines move large amounts of power at a high voltage level — a level that is too much to be delivered directly to a home or business.
In the first electric power station Pearl street Electric station in New York city went into operation. Electric Operating Systems Transmission Line vs Distribution Line Transmission Line - Normally carries electricity at voltages of 69 kV or greater and is used to transmit electric power over relatively long distances, usually from a central generating station to main substations. But sometime 3. Singh Electrical energy, being a very convenient form of energy, has become fully pervasive in the modern world. A primary distribution substation is the connection point of a distribution system to a trans-mission or a sub-transmission network.

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. Electrical energy, being a very convenient form of energy, has become fully pervasive in the modern world.

Growing loads and aging equipment are stressing the system and increasing the risk of widespread blackouts. Modern society depends on reliable and economic delivery of electricity. Moreover, effective and significant utilization of intermittent renewable generation located away from major load centers cannot be accomplished without significant additions to the transmission system.
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. Generators produce two type of power AC and DC. Electrical energy has grown immensely over two centuries because the flexibility it provides for its use.
An electrical grid , electric grid or power grid , is an interconnected network for delivering electricity from producers to consumers. It consists of: . Electrical grids vary in size from covering a single building through national grids which cover whole countries to transnational grids which can cross continents. Power stations connected to grids are often located near energy resources such as a source of fuel or to take advantage of renewable energy resources, and away from heavily-populated areas. A bulk-power transmission network is therefore used to move the power long distances, sometimes across international boundaries, until it reaches its wholesale customer usually the organisation that owns the local electric power distribution network. The electric power is therefore stepped up to a high voltage for the electric power transmission system. On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution-level voltage.
Стратмор холил и лелеял Сьюзан, оберегал. Он заслужил. И теперь наконец ее получит.
Шифровалка превратилась в наглухо закрытую гробницу. Но это теперь не имело никакого значения, мысль о смерти ее не пугала. Смерть остановит боль. Она будет опять рядом с Дэвидом. Шифровалка начала вибрировать, словно из ее глубин на поверхность рвалось сердитое морское чудовище.
Я сказала нет! - И, выдержав паузу, добавила: - И до вчерашней ночи это была правда. В глазах Сьюзан Дэвид был самим совершенством - насколько вообще такое .
Голос Дэвида точно вел ее, управляя ее действиями. Она бросилась к лестнице и начала подниматься к кабинету Стратмора. За ее спиной ТРАНСТЕКСТ издал предсмертный оглушающий стон.
Сьюзан заставила себя промолчать. Хейл хмыкнул себе под нос и убрал упаковку тофу.
Вы его запомнили. - Вы сказали, что он приходил. Беккер услышал, как его собеседница листает книгу заказов. Там не окажется никакого Клауса, но Беккер понимал, что клиенты далеко не всегда указывают свои подлинные имена.
Сразу же? - усомнилась Сьюзан. - Каким образом. Даже если Цифровая крепость станет общедоступной, большинство пользователей из соображений удобства будут продолжать пользоваться старыми программами.
