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
Three-phase — This article deals with the basic mathematics and principles of three phase electricity. For information on where, how and why three phase is used, see three phase electric power. In electrical engineering, three phase electric power systems have … Wikipedia
Single-phase electric power — In electrical engineering, single phase electric power refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single phase distribution is used when loads are mostly … Wikipedia
Two-phase electric power — Two phase electrical power was an early 20th century polyphase alternating current electric power distribution system. Two circuits were used, with voltage phases differing by 90 degrees. Usually circuits used four wires, two for each phase. Less … Wikipedia
Three-phase power — Power generated and transmitted from generator to load on three conductors. U.S. Dept. of Energy, Energy Information Administration s Energy Glossary … Energy terms
Split-phase electric power — A split phase electricity distribution system is a 3 wire single phase distribution system, commonly used in North America for single family residential and light commercial (up to about 100 kVA) applications. It is the AC equivalent of the… … 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
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
Phase — A phase is one part or portion in recurring or serial activities or occurrences logically connected within a greater process, often resulting in an output or a change. Phase or phases may also refer to:In science and engineering* Phase (matter),… … Wikipedia
Power outage — A power outage (also known as power cut , power failure , power loss , or blackout ) is the loss of the electricity supply to an area.The reasons for a power failure can for instance be a defect in a power station, damage to a power line or other … Wikipedia
Phase fired controllers — Phase control (PFC), also called phase cutting, is a method of pulse width modulation (PWM) for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode like devices into and out … Wikipedia
