New ideas for using data from insulation monitoring devices in the railway field

Abstract

Insulation monitoring devices are used in many parts of the transport network to raise safety levels. in railway engineering, many of these devices are installed in key items of infrastructure such as signal boxes. The limit values for these systems are monitored in accordance with regulations such as Corporate Derictive 892 issued by Deutsche Bahn Netz AG. This article provides ideas of how measurement data coming from insulation monitoring systems can be used to derive prognostic models and describes potential application in maintenance optimisation.
