Higher-level system for uniform condition assessment of medium-voltage power cables based on different diagnostic methods

该项目的目的是为中压电缆系统的统一状况评估创建一个评级系统，以便根据现场测量使用诊断方法生成有效、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。不同诊断方法对各种、众多现有相关情况(如局部放电、热老化等)的重要性也应该考虑到这一点。为了更好地利用有限的资源，基于底层诊断方法的状态指数是重要的依据。但是，状态指数必须具有可比性，并且独立于各自的中压电缆系统和所选的诊断方法。为了实现这一点，必须考虑诊断方法的不同特性和中压电缆的不同组成。该项目尤其涉及以下部分：识别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；生成考虑所有相关诊断方法的可比较的状态指数，并创建用于状态评估的统一系统

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
