In Table 99 some figures are given concerning the total electric energy
production in 1912. At the same time the total length of the long-distance
transmission lines, known to the inspectors of the State, amounted to 6 757 km.
From the figures given can be gauged the great importance of the
transmission of electric energy for the industrial development of the country, an
importance that will increase more and more with the progress of technics. The
highest tension in use is 50 000 volts, but at present (1914) some 80 000 and
100 000 volts transmission lines are about to be installed. In America, however,
experience has shown that there are no technical obstacles to tlie transmission of
