The aim of the project is the creation of a rating system for a uniform condition assessment of medium-voltage cable systems in order to generate valid, realistic assessment results based on on-site measurements using diagnostic methods. On the basis of the measurement results of the various known diagnostic methods, which provide different parameters, a comparable, uniform evaluation result will be generated. The significance of different diagnostic methods with regard to various, numerous existing relevant conditions (e.g. partial discharges, thermal aging, etc.) should also be taken into account. In order to use the limited resources optimally, condition indices based on underlying diagnostic methods represent an important basis. However, the condition indices have to be comparable and independent of the respective medium-voltage cable system and the selected diagnostic method. In order to achieve this, the different properties of the diagnostic methods and the individual compositions of the medium-voltage cables have to be taken into account.In particular, the following parts are pursued in this project: Identification of relevant processes that lead to a loss of substance; Determination of the significance of all relevant diagnostic methods used for condition assessment; Generation of comparable condition indices considering all relevant diagnostic methods and creation of a uniform system for condition assessment

该项目的目的是创建一个用于中压电缆系统统一状态评估的评级系统，以便基于使用诊断方法的现场测量生成有效，现实的评估结果。基于提供不同参数的各种已知诊断方法的测量结果，将产生可比较的、统一的评估结果。不同的诊断方法对于各种各样的现有相关条件（例如局部放电、热老化等）的重要性也应该考虑到。为了最佳地利用有限的资源，基于基本诊断方法的条件指数是一个重要的基础。然而，条件指数必须具有可比性，并且独立于相应的中压电缆系统和所选的诊断方法。为了实现这一目标，必须考虑到诊断方法的不同特性和中压电缆的各个组成部分，特别是在该项目中进行以下部分：确定导致物质损失的相关过程;确定用于状态评估的所有相关诊断方法的重要性;考虑到所有相关诊断方法，生成可比较的状况指数，并创建统一的状况评估系统
