Assessment of the remaining service life of plastic-insulated cable lines and mixed cable runs with focus on medium-voltage cables (10kV)

Topic:
Assessment of the remaining service life of plastic-insulated cable lines and mixed cable runs with focus on medium-voltage cables (10kV)
Describtion:
The liberalization of the electricity industry operators of power cable networks are under increased cost pressure while maintaining quality of care. In the future investments in the cable network have to be done with more efficiency than in the past. In the area of medium voltage networks in Berlin also exists a large proportion of PE-insulated cables from East German and Polish production with a graphitized conductive layer, which, under water influence,  is subject to damage by water in-trees which will shorten the life time significantly. The aim of this work is to present an appropriate and improved diagnostic technique, which 
serves as a basis for the condition assessment and a resulting long-term strategy for appropriate maintainance decisions.
