Fyodor Pirotsky

Fyodor Apollonowitsch Pirozki (Russian Фёдор Аполлонович Пироцкий; * 17 Februarjul / March 1 1845 Greg Ujesd Lochvitsa (Ukrainian Lochwyzja ) Gouvernement Poltava, .. † 28 Februarjul / March 12th, 1898 in Greg Oleschki / Олешки, government Tauria. . today Cyurupinsk (Russian Tsjurupinsk ) was a russian engineer of Ukrainian descent. He stood as an officer in the service of the artillery, but experimented in leisure with electricity, especially electrical drives.

Electric rail traction

From 1874 Pirozki experimented for several years with the transmission of electrical energy over long distances. As the subject of it was a disused one kilometers long siding in Sestrorezk. The rails were insulated from the ground. The power supply was carried out by a gram of ash DC generator. In the experiments, he found that smaller electric motors, can be, for example, for Loren, driven by this principle. In August 1876, he published his findings in the journal " Engineering Journal".

As of September 3, 1880 Pirozki led to an approximately 1 km long route suburb of Saint Petersburg tram network in St. Petersburg before his system. In one of the usual double-decker horse tram car he had built an electric motor and let him drive with its power on the track. He campaigned for his system, in which he referred to the low-cost conversion costs ( no masts, no center rail). 1881 his results were presented at the International Electricity Exhibition in Paris. After his system was opened in Brighton in the UK Volk's Electric Railway in 1883.

More life

Even before the web drive experiments he had designed an electric ventilation for baking ovens. In 1881 he moved the first underground power line from St. Petersburg. He published proposals for an underground central electricity supply.

In 1888 he resigned from the military and moved to Oleschki in southern Ukraine, where he lived from his state pension.
