Electric power

Electric power

  • Mains electricity
    Mains electricity is the general-purpose alternating-current (AC) electric power supply.
  • Electrical substation
    A substation is a part of an electrical generation, transmission, and distribution system.
  • Electricity meter
    An electricity meter, electric meter, electrical meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device.
  • Smart grid
    A smart grid is an electrical grid which includes a variety of operational and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficiency resources.
  • Magnetohydrodynamic generator
    A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic device that transforms thermal energy and kinetic energy into electricity.
  • Electrician
    An electrician is a tradesperson specializing in electrical wiring of buildings, stationary machines, and related equipment.
  • Alternating current
    Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction.
  • Direct current
    Direct current (DC) is the unidirectional flow of electric charge.
  • Electric power
    Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
  • Electric generator
    In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit.
  • Ground (electricity)
    In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.
  • Transmission tower
    A transmission tower or power tower (electricity pylon in the United Kingdom and parts of Europe) is a tall structure, usually a steel lattice tower, used to support an overhead power line.
  • Power engineering
    Power engineering, also called power systems engineering, is a subfield of energy engineering and electrical engineering that deals with the generation, transmission, distribution and utilization of electric power and the electrical devices connected to such systems including generators, motors and transformers.
  • AC power plugs and sockets
    AC power plugs and sockets are devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building.
  • Power over Ethernet
    Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electric power along with data on twisted pair Ethernet cabling.
  • Space-based solar power
    Space-based solar power (SBSP) is the concept of collecting solar power in space (using an "SPS", that is, a "solar-power satellite" or a "satellite power system") for use on Earth.
  • Three-phase electric power
    Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution.
  • Magnetic amplifier
    The magnetic amplifier (colloquially known as a "mag amp") is an electromagnetic device for amplifying electrical signals.
  • Electricity retailing
    Electricity retailing is the final sale of electricity from generation to the end-use consumer.
  • Lineman (technician)
    A lineman (American English) or linesman (British English), also occasionally called a lineworker, powerline technician (PLT), or a powerline worker, is a tradesman who constructs and maintains electric power transmission and distribution facilities.
  • CPU power dissipation
    Central processing unit power dissipation or CPU power dissipation is the process in which central processing units (CPUs) consume electrical energy, and dissipate this energy both by the action of the switching devices contained in the CPU (such as transistors or vacuum tubes) and by the energy lost in the form of heat due to the impedance of the electronic circuits.
  • Electric power industry
    The electric power industry is the generation, transmission, distribution and sale of electric power to the general public.
  • Load profile
    In electrical engineering, a load profile is a graph of the variation in the electrical load versus time.
  • Electric potential energy
    Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
  • Utility frequency
    The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency of the oscillations of alternating current (AC) in an electric power grid transmitted from a power plant to the end-user.
