Three Phase Electric Power Inventor

Prior to this all commercially produced motors were dc utilizing expensive commutators and high maintenance brushes prone to malfunction and not usable for operation on an alternating current network.

Three phase electric power inventor. 3 4 5 6 9 twentieth century edit. Polish russian engineer and inventor. The three phase induction motor was developed by mikhail dolivo dobrovolsky in 1889. In electrical engineering three phase electric power systems have at least three conductors carrying alternating current voltages that are offset in time by one third of the period.

1889 dobrovolsky builds his first transformer and motor to work with his 3 phase ac system. Tesla s mother đuka mandić 1822 1892 whose father was also an orthodox priest had a talent for making home craft tools and mechanical. A three wire three phase circuit is usually more economical than an equivalent two wire. The modern 3 phase system was developed by mikhail dolivo dobrovolsky and allgemeine elektricitäts gesellschaft and charles eugene lancelot brown in europe starting in 1889.

This is one of the most important innovations contributed by nikola tesla 1856 1943 because it enabled more efficient and simplified energy generation and transmission. Nowadays the three phase system serves as the basis of most electrical systems which consist of energy generation transmission and consumption. In 1891 he invented the tesla coil an induction coil widely used in radio technology. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.

The international electro technical exhibition of 1891 in frankfurt germany featured the long distance transmission of high power three phase electric current. A wye system allows the use of two different voltages from all three phases such as a 230 400 v system which. It is also used to power large motors and other heavy loads. Induction motors using a rotating magnetic field were independently invented by galileo ferraris and nikola tesla and developed in a three phase form by mikhail dolivo dobrovolsky in 1889.

He also developed the three phase system of electric power transmission. He immigrated to the united states in 1884 and sold the patent rights to his system of alternating current dynamos transformers and motors to george westinghouse. A three phase system may be arranged in delta or star y also denoted as wye in some areas. This one was created for the electrical exposition in frankfurt germany in 1891.

Nikola tesla was born an ethnic serb in the village of smiljan within the military frontier in the austrian empire present day croatia on 10 july o s. Three phase electric power is a common method of alternating current electric power generation transmission and distribution.
