Step Up Transformers

A reliable source for Electric Transformers information and leading Electric Transformers Companies & Manufacturers.

Step up transformers are a very common tool used in power transforming and modification applications; they are typically the first major transformer in a power transmission system and are often used in multiple locations throughout the system. An example of this would be in power plants. Read More…

Step Up Transformers Step up transformers have the power to convert low voltages to higher voltages while reducing both amperage and the effects of resistance. This conversion occurs by means of transferring electrical energy through two coil stages, the second coil stage having more coil windings than the first.

Electricity loses energy traveling down power lines; however, high voltage electricity loses less energy than electricity at low voltages. As a result, power plants boost, or step up, the generated electricity to an extremely high voltage before it leaves the power plant so that less electrical energy will be lost. In addition, foreign business travelers often use step down transformers for conversion to North American voltages for safe use of laptops, fax machines, cellular phones and answering machines, without worrying about short-circuiting, blowing equipment or starting a fire.

Materials used to construct the coil windings include copper, special steel alloys, chromium, nickel and aluminum, of which copper windings are the most efficient as well as being a little more costly. Sizes of step up transformers range from large devices intended for use in electrical power systems to much smaller units used in electronic equipment such as loudspeakers in radios, high fidelity equipment and television sets.

A step up transformer is comprised of two sets of coils or windings linked by a magnetic field. The core can be made of a ferrite compound or a laminated core wound with bare copper or enameled coils. The coils are primary and secondary and function as conductors. The principal function of a step up voltage transformer is to convert low voltage, high current power into high voltage, low current power. Although there is no connection between the two circuits, the coil windings are inductively linked. The primary coil serves as the input and is linked to a power generator, while the secondary coil serves as the output and is linked to the load or loads.

The conversion begins when the primary coil receives alternating current, or AC, voltage, this produces a varying magnetic field of voltage surrounding the conductor; the magnetic field activates the secondary conductor coil. Once the voltage conversion is made, the energy is transferred to the load center and the electrical process continues from there.

The ratio of turns (also known as windings) in the primary coil to the number of turns in the secondary coil determines the magnitude of the voltage; in a step down transformer there will be more turns in its secondary coil than the primary. Even though there are fewer turns, the turns in the primary coil are of a larger gauge wire than used in the secondary coil in order to handle the increased current power that has been transferred to the primary coil. The ratio of the voltage between the windings of the primary and the secondary circuit mirrors the ratio of the number of windings.
