In the late 1950s and early 1960s, when computers were almost non-existent and unaffordable, the research station was equipped with electrical measurement and control equipment that may seem outdated today but was state of the art at the time. The station had the honour of being visited by Francis Perrin then High Commissioner for Atomic Energy, and by the Engineer General of Maritime Engineering, Albert Caquot in charge of the Rance dam project (1961-1966). Note: the three-phase 220~380 volts / 50Hz current that is distributed today in France was not yet distributed in those years. The station was supplied with three-phase 127~220 volts / 50 Hz by the step-down transformer. (Click on the pictures to see their actual size). |
