11Rectifier — A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers …
12Quadrature booster — A quadrature booster, also known as a phase shifting transformer or more simply a quad booster, is a specialised form of transformer used to control the flow of real power on three phase electricity transmission networks. For an alternating… …

14Pylon transformer — Because of weight restrictions transformers for pylon transformers are only built for voltages under 30kV.Pylon transformers are often used for the power supply of facilities outside settlements, such as farmyards or pumping stations at voltages… …
15Ground and neutral — For uses of the term ground or earth in electricity but not in the context of mains wiring, see ground (electricity). Since the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely… …
16Tweeter — A tweeter is a loudspeaker designed to produce high frequencies, typically from around 2,000 hertz to 20,000 hertz (20,000 Hz, generally considered to be the upper limit of the human hearing). A few tweeters can manage response up to an octave or …
17Push–pull converter — A push–pull converter is a type of DC to DC converter that uses a transformer to change the voltage of a DC power supply. The transformer s ratio is arbitrary but fixed; however, in many circuit implementations the duty cycle of the switching… …
18High leg delta — A high leg delta (also known as wild leg or red leg delta) is a type of electrical service connection sometimes found in older three phase electric power installations. This type of service is supplied by a transformer having four wires coming… …
19Mercury 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… …
20Mercury-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… …
