EHIGHWAY. As part of the accompanying scientific research also the aging behavior of the insulators on the eHighway system, as these are subject to heavy loadsen e.g. due to salt spray in winter.

Measuring systems for recording leakage currents were developed last year and integrated into the system. During the maintenance work carried out in Septemberthese measuring systeme with additional special sensors for permanentn and continuousn Recording of the prevailing boundary conditions extended. With the now in the roadway and on the overhead line sensors installed in the roadway and on the liquid filme on the road and the traffic caused by thening spray mist in the air analyze.

The investigations are being carried out by the Technical University of Dresden together with Siemens Mobility GmbH and by the R&D-Center and Autobahn GmbH supported. The The results should be incorporated into ongoing standardization processes for insulators and could also bring new insights for road operations.
