The transformer is an electronic device that converts voltage by magnetic coupling without moving parts. It consists of a magnet core and two or more coupled winds that either step up or down the incoming current voltage. This is accomplished by the transfer or energy between the circuits through the magnetic center. These windings are commonly called Primary and Secondary windings. The electromagnetic field created by the above process expands and collapsing around conductor, changing the induced voltage. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.
Only two sets of windings will be considered in order to fully understand the functions of a Transformer. When AC voltage is applied to an input device for such an electrical device the primary winding generates alternating current that creates magnetic flux in its core. This causes an AC voltage to the secondary coil. This is the step up/step down voltage of your device. Step up and step down refer to the input voltage. You will need a stepdown transformer to power your equipment if the input voltage of your equipment is 110 Volts AC.
The high tension transmission of power, in which huge towers carry cables carrying the power, uses step-up transformers. When the power leaves the stations, it is reduced to the necessary mains supply. The reason power is increased as it leaves the power station is that there are power losses as the power travels down long power cables. As such, power can reach destinations at a specified power level. There are many uses for transformers in this application.
The transformer is the simplest electrical device. Although its fundamental principle has not changed over the past 100 year, both the material and its design have improved. It plays a vital role in the conversion of electrical energy for power transmission and for consumer use. Audio frequency transformers were also used in the early development of telephones. These can still be found in many electronic devices. The size of the transformer depends on its purpose. The transformer can be as small as a thumb nail or large enough to power transmission applications in national power grids. They all work on the same principle.
