An electric power systemis a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical gridthat provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the generatorsthat supply the power, the transmission ...
Examples include automated manufacturing systems, [83] heating, ventilation and air-conditioning systems, [84] and various subsystems of aircraft and automobiles. [85] Electronic systems design is the subject within electrical engineering that deals with the multi-disciplinary design issues of complex electrical and mechanical systems. [86]
For example, a subway rapid transit electrical system is composed of the wayside electrical power supply, wayside control system, and the electrical systems of each transit car. Each transit car’s electrical system is a subsystem of the subway system. Inside of each transit car there are also subsystems, such as the car climate control system.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. [ 1 ]Primary ...
Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ[ 1 ]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [ 2 ] It is a type of polyphase system employing three wires ...
Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution, and utilization of electric power, and the electrical apparatus connected to such systems. Although much of the field is concerned with the problems of three-phase AC power – the ...
A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with ...
A relay is a common electro-mechanical device. Electromechanics[1][2][3][4]combines processes and procedures drawn from electrical engineeringand mechanical engineering. Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other.
