A practical framework is presented to connect technical reliability effects in medium-voltage (MV) cable networks with financial outcomes that matter for Distribution System Operators (DSOs) and solution providers. The work was carried out within Nexans’ grid-reliability activity and focuses on online MV cable monitoring based on Smart Cable Guard (SCG). The central idea is simple: feeder operational investments (those that affect positively faults, weak-spot restorations, downtime, and interruptions) are translated into annual cash flows and standard investment metrics. To make this translation transparent, the restoration process is decomposed into the stages that typically drive time and cost (localization; administrative and street-works; excavation and reinstatement; electrical repair and testing).
