A few years later, Frenchman Lucien Gaulard and John Dixon Gibbs of England demonstrated a transformer, which they called a “secondary generator,” in London. William Stanley designed the first commercial transformer for Westinghouse in 1886. A transformer changes a given electrical current into another current of different voltage. Today AC systems and transformers that follow the same basic design as Stanley’s continue to supply almost all the world’s power. The other components merely make this power available in a suitable, reliable form. However, this is one of those devices that was not really invented by any single person. In a non-ideal transformer, however, there are power losses due to resistive heating in the windings. The transformer is one of the key inventions fundamental to creating the electrified world. A native of Brooklyn, New York, Stanley studied at Yale University, where he abandoned plans for a legal career to pursue a dream of electrical invention. The same would happen if we asked who conceived the internal combustion engine, the electric motor, the telegraph, the telephone, the radio, the television, or the computer. Michael Faraday showed that current in one coil can be induced in another, thus discovering the underlying working principle of a transformer. What is powering a multitude of electronic equipment that we can’t do without. Transformers are commonly made by winding two coils around an iron core. In an ironic twist of history, Stanley was awarded the Edison Medal (named in honor of the great inventor) by the American Institute of Electrical Engineers in 1912 for work that helped cement the defeat of Edison’s DC system. Transformers only work with alternating current and are typically formed from coupled coils of wire wound around a metallic core. Stanley’s feat proved that high voltage transmission was practical and safe. All rights reserved. Supply voltages needed to drive a myriad of electronic gadgets and equipment. Become a Study.com member to unlock this In the G1 cartoon and movie, the Transformers are created by the Quintessons, another robot-like species.They created the Autobots as laborers and the Decepticons as their military. Step-down transformer to decrease the voltage. - Who Invented First, Food Inventions and Who Did Them? Who invented the quick freezing process of... How did the lightbulb change American life? For a step-up transformer, if the secondary has twice as many turns, then by proportion, the seconday voltage must be twice the primary voltage. The reader may be interested in more details on this topic or to learn about power transmission and usage. Their function? Required fields are marked *. Using numbers, if the primary has 5000 turns and the secondary has 500 turns, then the turns ratio is 10:1. After getting his feet wet as an electrician, he worked as an assistant to inventor Hiram Maxim, whose electrical innovations made him a rival of Thomas Edison. This requirement is precisely the function of the transformer! Also, the parallel linkage of the transformers ensured that performance was relatively stable; any changes in load on one transformer did not affect the others. : A transformer brings the voltage of a current in a circuit up or down. Who Invented the Transformer? The slower pace of life allowed him time to transform his dream into a reality. Create your account. His achievements distinguished Stanley among others in the burgeoning electric industry and gained him the important position with Westinghouse. Center for Integrating Research + Learning. Funded by the National Science Foundation Division of Materials Research (DMR-1644779) and the State of Florida Any opinions, findings and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. In the example, the power supplied would be somewhat smaller, say 22.6 watt for 5% losses. While the Gaulard-Gibbs transformer demonstrated significant promise, Westinghouse asked the chief engineer in his Pittsburgh factory, William Stanley, to improve its design. Where did George Stephenson go to school? Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Sciences, Culinary Arts and Personal Power supplies are very important in electronics and in our everyday lives, supplying voltages and currents necessary for circuits to operate. A transformer is an electrical device that transfers energy from one circuit to another purely by magnetic coupling. The modern transformer is normally located inside the power supply. In 1890, Stanley ventured out on his own to form the Stanley Electric Manufacturing Company. In the late 1870s, Pavel Yablochkov built a system of electric candles that used induction coils that functioned as transformers. Abstract: If we were to ask who invented the transformer, we would obtain different answers from different countries. On March 20 of that year, he publicly demonstrated its use as part of an AC electric system that provided power to the businesses along Great Barrington’s Main Street. However, this device was quite basic and wasn't suited for commercial... Our experts can answer your tough homework and study questions. So, if the primary voltage is 240 volts then the secondary voltage will be smaller by this same ratio, to 24 volts. The origin in the comics and subsequent series differs, but here is one of the more accepted/referenced ones: Primus is brother to Unicron. DC could not be safely transmitted very far because there was no way to increase or decrease voltages. Transformers only work with alternating current and are typically formed from coupled coils of wire wound around a metallic core. While working on his transformer design in 1885, Stanley fell ill. On his doctor’s advice, he moved from the city to live with family in Great Barrington, Massachusetts. How did George Stephenson's railroad make things...

Applying discoveries Michael Faraday had made a few decades earlier, William Stanley designed the first commercial transformer for Westinghouse in 1886. If we were to ask who invented the transformer, we would obtain different answers from different countries. Any transformer simply consists of two coils positioned so that the magnetic flux from one passes through to the other. The answer is, a transformer as the central piece inside any power supply. This is not surprising because, in several cases, the priority of inventions that occurred … With Maxim, Stanley helped implement an electrical system to provide power to a shop on New York’s Fifth Avenue, one of the first of its kind. FROM THE NATIONAL HIGH MAGNETIC FIELD LABORATORY. Nearly half a century passed, however, before the principle was applied to commercial purposes, rather than just scientific research. A transformer makes it possible to step up (increase) the voltage of a current in order to transmit it, then to step it down (decrease) to power lights, appliances, etc.
