Delta-wye transformer — Not to be confused with Y Δ transform. A delta wye (Δ Y) transformer is a transformer that converts three phase electric power without a neutral wire into 3 phase power with a neutral wire. It can be a single three phase transformer, or built… … Wikipedia
Distribution transformer — Single phase distribution transformer in Canada A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the… … Wikipedia
Zigzag transformer — A zigzag transformer is a special purpose transformer. It has primary windings but no secondary winding. One application is to derive an earth reference point for an ungrounded electrical system. Another is to control harmonic currents.As with… … Wikipedia
Pylon 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… … Wikipedia
Y-Δ transform — For application in statistical mechanics see Yang Baxter equation. For the device which transforms three phase electric power without a neutral wire into three phase power with a neutral wire, see delta wye transformer. The Y Δ transform, also… … Wikipedia
Polyphase system — A polyphase system is a means of distributing alternating current electrical power. Polyphase systems have three or more energized electrical conductors carrying alternating currents with a definite time offset between the voltage waves in each… … Wikipedia
Mains power systems — This article includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. For definitions of terms and further information on each… … Wikipedia
Mains electricity by country — This article includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. For definitions of terms and further information on each… … Wikipedia
Ground 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… … Wikipedia
Ferroresonance — The phenomenon of Ferroresonance is the occurrence of an unstable high voltage, typically on 3 phase electrical systems which only occurs under specific conditions. The nature of the overvoltage can cause the failure of equipment.Ferroresonance… … Wikipedia
Electricity 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 … Wikipedia
