Extended Approach for Calculating Thermal Stress and Ampacity of High Voltage Cable Systems Based on Experimental Data

Research output: Contribution to conferencePaper

Abstract

Thermal rating calculations of high voltage cable systems
are normally performed using either analytical or numerical
methods. Nevertheless, both methods face problems
through simplifications, approximations or the insufficient
modelling of the surrounding soil. The High Voltage Test
Laboratory Graz Ltd. is currently developing an extended
approach, which combines these methods for higher
accuracy. The research so far shows, that a more detailed
modelling of the cable structure and the soil as well as
dynamic boundary conditions can increase accuracy.
