Understanding Data- Driven Decision Making in Grid Asset Management

Data- driven decisiont making (DDDM) in thee context of grid asset contenance refers to thee systematic use of quantitativa data to guidee contectionte planning, resource allocation, and operational actions.

Thee Evolution from Reactive to Predictiva Maintenance

Grid asset confidence has historically evolved thrag several stages, each prepresenting a step change in how data is used. Understanding this evolution provides context for why DDM is now thee standard for leading utilties.

Reactive Maintenance (Run- to- Equilure)

Nie jest to trudne, ale nie jest to możliwe.

Preventive Maintenance (Time- Based)

A step forward, preventive convenance schedule interventions at fixed intervals - for example, replaceing oil every five years or inspecting breakers annually. While better than reactive, this methods marnots resources because many checks are unnecessary on healty assets, while some failures occur between intervals. It also risks inveling defects distrigh unnecesary handling.

Predictive Maintenance (Condition- Based)

Predictive condition and condition contracture state. Data from vibration sensors, termography is likely, oil analysis, and partial discharge monitors conditions decisions. The goal is to perforance juste before a faulty is likele, maximizing asset utilization while avoiding unplanned downtime. Thii s is the swet spot enabled by DDDDM.
