Background

Dolivo-Dobrovolsky has constructed three-phase motor and electrical system, which is transmitted by three-phase voltage of 8500 V, a capacity of 220 kW at a distance of 175 km.Pervym found that the most economical way to transfer energy to a distance - EHV millions of volts DC.

Mikhail Osipovich studied at the Riga Polytechnic Institute, and was expelled from it for political activities without the right to admission to any institution of higher education in Russia. So he went to study in Germany, where he brilliantly graduated from the Higher Technical School.

In 1889 Dolivo-Dobrovolsky has constructed three-phase motor and electrical system, which is transmitted by three-phase voltage of 8500 V, a capacity of 220 kW at a distance of 175 km. He built it very quickly, in just one year.

But Mikhail Dolivo-Dobrovolsky - AC connoisseur - not rejected the values ??of DC. He first discovered that the most economical way to transfer energy to a distance - EHV millions of volts DC.
