31Three-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… …
32Two-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 …
33Mercury arc valve — A mercury arc valve (mercury vapor rectifier) is a type of electrical rectifier which converts alternating current into direct current. Rectifiers of this type were used in electric motor power supplies for industry, in electric… …
34Mercury-arc valve — Mercury rectifier on display in Beromünster, Switzerland before being decommissioned A mercury arc valve (mercury vapor rectifier) is a type of electrical rectifier used for converting high voltage or high current alternating current (AC) into… …
35Alternator — s are called turbo alternators.HistoryAlternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current. The early machines were developed by pioneers such as Michael Faraday and… …
36Diode bridge — Three bridge rectifiers. The size is generally related to the current handling capability …
37Electricity distribution — is the penultimate stage in the delivery (before retail) of electricity to end users. It is generally considered to include medium voltage (less than 50 kV) power lines, electrical substations and pole mounted transformers, low voltage (less than …
38Magnetic amplifiers (history) — The magnetic amplifier (sometimes called a self saturated amplifier ) is a magnetic device consisting of a saturable reactor (transformer) modulated by a direct current. This DC current is introduced in the primary winding of an iron core… …
