ELECTRIFICATION STUDY
The Engineer Dorin Pavel, „the father” of the Romanian hydroenergetic,
has published in 1925, as Assistant Professor at Zürich Technical
University, an „Electrification Study”. The study was related to the Romanian
Railways and it was printed in the General Romanian Engineering Association
(AGIR) magazine. After analyzing different electrification systems in Europe
and not only, he concluded: „I’m not an enthusiastic of the single-phase Swiss
system, but I think that the most efficient way would be to transform the 50
cycles three-phase current into 50 cycles single-phase current”. What
clairvoyance! The Congress of Lille recommended only in 1955 to use 25 kV,
50 Hz in new railway electrification works. The study continues with a proposed
schedule to electrify the CFR network in three 8 years stages, with the first
section between Bucharest and Brasov. So it was, but 35 years later: the first
overhead pole was erected in Predeal station on December 27, 1960. The last
part of the study shows the necessary power supply, based mainly on the
Romanian hydro potential.
