Abstract
In order to maintain a reliable LV distribution grid (an important building block in the energy transition) DSOs are looking into ways to investigate the condition of LV grid components. A survival analysis method – Cox Proportional Hazard regression – was used to investigate relations between variables and the failure probability of LV cables and joints. In this paper the results of this approach are interpreted. The results provide much insight and can be explained by experts and are supported by experts in the electricity distribution sector. The results can be used to rank individual assets on a relative failure probability, which is based on the values of the aforementioned variables. This study is a first step towards improved asset management strategies.
