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对中压电缆系统进行统一状态评估的评级系统，以便根据诊断方法的现场测量生成有效、现实的评估结果。各种已知的诊断方法提供不同的参数，也应该产生可比较的、统一的评估结果，不同的诊断方法对于各种、大量现有的相关条件（例如局部放电、热老化等）的意义。考虑到利用有限的资源。最佳情况下，基于基础诊断方法的状态指数是重要的基础，但是，状态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。必须考虑到中压电缆的诊断方法和单独的成分。该项目特别追求以下部分： - 识别导致物质损失的相关过程； - 确定使用的所有相关诊断方法用于状况评估；​​考虑所有相关诊断方法，生成可比较的状况指数，并创建统一的状况评估系统
