Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers.
The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry.
The degree to which voltage, frequency and waveform comply with established standards.
The bulk movement of electricity from one site to another.
The concept of electric propulsion is over 100 years old with battery-powered vessels recorded in Russia and Germany around 1870. In 1893, one of the first electric boats ELECTRICITY carried passengers on the River Thames in England.
Electrical injury is a physiological reaction caused by electric current passing through the body. The injury depends on the density of the current, tissue resistance and duration of contact.
The interconnected lines which facilitate the bulk movement of high voltage electricity are known as a transmission network.
Admittance is a measure of how easily a circuit or device will allow a current to flow.
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces a prolonged electrical discharge.
A short circuit when two lines come into contact with the ground (and each other) commonly due to storm damage.
A short circuit between one line and ground, very often caused by physical contact, for example due to lightning or other storm damage.
A short circuit between lines, caused by ionization of air, or when lines come into physical contact, for example due to a broken insulator.
A fault where all the conductors are considered connected to ground as if by a metallic conductor. In one type of transmission line protection, a "bolted fault" is deliberately introduced to speed up operation of protective devices.
Braking of a small wind turbine can be done by dumping energy from the generator into a resistor bank, converting the kinetic energy of the turbine rotation into heat.
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current.
An electrical circuit is a network consisting of a closed loop, giving a return path for the current.
Electrical conductance is the ease with which an electric current passes.
An electrical conduit is a tube used to protect and route electrical wiring in a building or structure.
An electrical connector is an electromechanical device used to join electrical conductors and create an electrical circuit.
An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal.
