Nouvelles possibilités d’étalonnage en puissance électrique au LNE

Abstract. The directive of European railway interoperability promotes the movements of trains on any rail network without any difference, including networks in different states. The energy consumed must be measured for each train in any state. In Europe, the electrification of train can be done by either a high DC voltage or a high AC voltage at frequencies of 50 Hz and 16 Hz 2/3. LNE has a good expertise in DC high voltage measurements and in AC high voltage measurements at frequency of 50 Hz but not for the frequency of 16 Hz 2/3. This article presents, then, an overview of the work that has been done or that is actually in progress in LNE to ensure the traceability of measurements at frequency of 16 Hz 2/3, frequency of railway electrification in Germany, in Switzerland and in Austria. The work mainly concerns the generation and the measurements of a high voltage up to 30 kV, the current measurements up to 250 A, the active and the reactive power measurements and the low voltage measurements up to 1000 V.
