The Common Information Model (CIM) is an electric power transmission and distribution standard developed by the electric power industry. It aims to allow application software to exchange information about an electrical network. [1] It has been officially adopted by the International Electrotechnical Commission (IEC).

A diagram of an electric power system. The transmission system is in blue. Most North American transmission lines are high-voltage three-phase AC, although single phase AC is sometimes used in railway electrification systems. DC technology is used for greater efficiency over longer distances, typically hundreds of miles.
A power outage (also called a power cut, a power out, a power blackout, power failure or a blackout) is a loss of the electric power to a particular area. Power failures can be caused by faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit , cascading failure ...
The electrical grid can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centers to the load centers, and the distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings ...
This category lists specific, individual electric power transmission systems. These typically operate at half-a-million or more volts , and run cross-country or even between countries. They should not be confused with electric power distribution grids, which are low-voltage systems that distribute power within a city, or rurally, to individual ...
Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power may be greater than the real power(pf ≤0.5). In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the ...
Electric transmission may refer to: Electric power transmission, the bulk movement of electrical energy from a generating site Diesel–electric transmission, a transmission system for vehicles powered by diesel engines; Petrol–electric transmission, a transmission system for vehicles powered by petrol engines
