Three Phase Electric Power Inventor

Polish russian engineer and inventor.

Three phase electric power inventor.

It is also used to power large motors and other heavy loads. 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. Invented the first cage and wound rotor versions of the three phase induction motor that are still widely in use today. 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.

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. A three phase system may be arranged in delta or star y also denoted as wye in some areas. One of the first three phase ac generators in the world.

His father milutin tesla 1819 1879 was an eastern orthodox priest. Three phase electric power is a common method of alternating current electric power generation transmission and distribution. 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. A wye system allows the use of two different voltages from all three phases such as a 230 400 v system which.

1889 dobrovolsky builds his first transformer and motor to work with his 3 phase ac system. The three phase induction motor was developed by mikhail dolivo dobrovolsky in 1889. Tesla s mother đuka mandić 1822 1892 whose father was also an orthodox priest had a talent for making home craft tools and mechanical. In 1891 he invented the tesla coil an induction coil widely used in radio technology.

He also developed the three phase system of electric power transmission. 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. 3 4 5 6 9 twentieth century edit. 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.

It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. A three wire three phase circuit is usually more economical than an equivalent two wire.
