Localisation of short circuits in the overhead contact line network of ÖBB using optical fibres

Overview

  • No accurate detection of the location of the short circuit with conventional technologies
  • Research on short circuit localisation using an optical fibre installed parallel to the line
  • Initial results show that short circuits can be localized accurately to 10 m

Abstract

Every year thousands of short circuits occur in the overhead contact line network of the ÖBB. Conventional technologies cannot accurately detect the location of the short circuit. In collaboration with Frauscher Sensortechnik GmbH, ÖBB conducts research on short circuit localisation using an optical fibre installed parallel to the line. Initial results show that short circuits can be localised accurately to 10 m.
