The first experiments to transmit electrical power over long distance were made by Marcel Deprez, at Creil, in 1876 to 1886, and Deprez succeeded in transmitting mechanical power thirty-five miles for industrial purposes in the latter year.
Marcel Deprez was born on December 12, 1843, in Aillant-sur-Milleron, Loiret, France.
This galvanometer was proposed by d'Arsonval in collaboration with Deprez is also defined as a mobile bobbin galvanometer and differs from those with a mobile magnet in that it is based on the interaction between a fixed magnet and a mobile circuit followed by the current being measured.

 Marcel Deprez - Wikipedia, the free encyclopedia
Marcel Deprez (December 12, 1843 - October 13, 1918) was a French electrical engineer.
At the International Exposition of Electricity, Paris in 1881, Deprez undertook the task of presenting an electricity distribution system based on the long-distance transport of direct current.
Deprez eventually attained transmission that were over thirty-five miles for industrial purposes.

For the latter purpose the shot successively cuts insulated wires fixed in plugs screwed into the gun at known intervals; each wire forms a part of the primary of an induction coil, and as each is cut a dot is made on the rotating drum by the induced spark.
In the chronograph of Marcel Deprez, a cylinder for receiving records is driven at a high velocity, 4 to 5 metres per second surface.
The velocity is determined by means of an electrically-driven tuning-fork, the traces being read by means of a vernier gauge.

Marcel Deprez had, it was well known, lately succeeded in transmitting as much as three horse power to a distance of 40 kilometers (25 miles) through a pair of ordinary telegraph wires of 4 millimeters in diameter.
But Deprez had employed a motor-dynamo of 2,000 volts, and was contented with a yield of 32 per cent.
This was to the effect that electricity was conveyed at the cheapest rate through a conductor, the cost of which was such that the annual interest upon the money expended equaled the annual expenditure for lost effect in the conductor in producing the power to be conveyed.

 Dynamometer - LoveToKnow 1911
This form of brake was also invented independently by J. Carpentier, and the principle has been used in the Raffard brake.
A self-compensating brake of another kind, by Marcel Deprez, was described with Carpentier's in 1880 (Bulletin de la societe d'encouragement, Paris).
Ayrton and J. Perry used a band or rope brake in which compensation is. effected by the pulley drawing in or letting out a part of the band or rope which has been roughened or in which a knot has been tied.

 The Project Gutenberg eBook of Scientific American Supplement, December 29, 1883
But let us look at the other side also.
Only a short time since the illustrious French physicist, M. Tresca, was enumerating the various sources of loss in the transmission of power by electricity along a fixed wire, as elucidated in the careful and elaborate experiments inaugurated by M. Marcel Deprez, and subsequently continued by himself.
These losses--the electrical no less than the mechanical losses--are being thoroughly and minutely examined in the hope of reducing them to the lowest limit; and this examination cannot fail to throw much light on the exact distribution of the energy imparted to a dynamo machine and the laws by which this distribution is governed.
