Three-phase electric power — This article deals with where, how and why three phase is used. For information on the basic mathematics and principles of three phase, see three phase. Three phase electric power is a common method of alternating current electric power… … Wikipedia
Electric power transmission — Electric transmission redirects here. For vehicle transmissions, see diesel electric transmission. 400 kV high tension transmission lines near Madrid Electric power transmission or high voltage electric transmission is the bulk transfer of… … Wikipedia
Power engineering — Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission and distribution of electric power as well as the electrical devices connected to such systems… … Wikipedia
History of electric power transmission — In the early days of commercial use of electric power, electric power transmission restricted the distance between generating plant and consumers. Originally generation was with direct current, which could not easily be increased in voltage for… … Wikipedia
Phase converter — A phase converter is a device that converts power provided as single or multiple phases to a different number of phases.The majority of phase converters are used to produce three phase electrical power from a single phase source, thus allowing… … Wikipedia
Power system simulation — models are a class of computer simulation programs that focus on the operation of electrical power systems. These computer programs are used in a wide range of planning and operational situations including: #Long term generation and transmission… … Wikipedia
Power system protection — is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the … Wikipedia
Transmission tower — A delta pylon carrying a 400kV power line towards Madrid. A transmission tower (colloquially termed an electricity pylon in the United Kingdom and parts of Europe, an ironman in Australia, and a hydro tower in parts of Canada) is a tall structure … Wikipedia
Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port … Wikipedia
Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… … Wikipedia
Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… … Wikipedia
