Biography of mahatma gandhi The associated asynchronous motor invented by him was the first functional solution. The first AC 3 phase synchronous generator went into operation in October To a various sort of measuring means has successfully applied a principle of the engine with rotating magnet field September 1 it has arrived in the Riga polytechnical institute, but has been excluded for participation in political performances of students.

The triumph of the three-phase system was displayed in Europe at the International Electro-Technical Exhibition of , where Dolivo-Dobrovolsky used this system to transmit electric power at the distance of km with 75% efficiency.
