“…It is unlikely this number will increase significantly very suddenly. Also, failure is mainly not age-related, as previously described [3], and components almost never degrade internally. Therefore, it is also unlikely that entire generations will fail in a short period.…”

“…In survival analysis, this metric is generally called "time-to-event," where an event could be failure, hospitalization, or death. As previously described [3], failures of underground LV cables are generally not age-related. Therefore, we are not interested in the specific moment at which an average asset fails; instead, we are more interested in the variables indicative of an increased failure probability.…”

“…For purposes of asset management (AM), it is relevant to investigate whether assets degrade over time and-if this is the case-at what speed this degradation takes place. However, we know from practice that underground LV cables and joints have a technical lifetime of many decades and failures are generally not age related [3]. Therefore, it is beneficial to be able to assess the condition of cables in order to optimize AM in LV cable grids.…”

Low voltage distribution grids play an important role in the energy transition-both in generation and demand. In the coming decades the reliability of these grids may deteriorate due to asset ageing. Various maintenance (replacement) strategies are compared in order to mitigate this. For multiple scenarios, it is analysed under which circumstances and when alternative strategies are more profitable than current practice towards managing low voltage assets. Under all scenarios utilities are advised to actively seek collaboration with other utilities and institutions in order to increase efficiency, reduce nuisance, achieve future-proofness and minimise risks. Also, opportunities for condition-based approaches exist with the increasing application of distribution automation.
