[UC58] Asset Maintenance History and Inspection Records Analysis

The Utility Problem

Every distribution asset accumulates a history over its operational life — a record of maintenance interventions, inspection findings, outage involvements, and condition assessments. This history is one of the most valuable sources of insight available to an asset manager: an asset that has required repeated corrective maintenance, appeared in multiple outage records, or shown a consistent pattern of degrading inspection results is telling a story about its reliability trajectory. Acting on that story early — before the next failure — is the core promise of condition-based and predictive asset management.

In practice, however, this history is rarely accessible in a coherent, asset-centric form. Maintenance records live in the work order management system. Outage involvement is recorded in the OMS. Inspection results may exist in a separate inspection management system, a shared drive of PDFs, or paper files in a district office. These systems are not integrated, and none of them provides a unified, chronological view of everything that has happened to a specific asset over its lifetime. When an engineer wants to investigate a suspect transformer or cable section, they must manually pull records from multiple systems, cross-reference asset identifiers that may not be consistent across those systems, and assemble the history by hand — a process that can take hours for a single asset.

The inability to efficiently query asset history also means that recurring issues go unrecognized at scale. A fuse that has been replaced three times in five years, a cable section that appears in outage records every winter, or a transformer that has failed inspection on consecutive cycles — these patterns exist in the data but are invisible without a system capable of filtering and aggregating maintenance and inspection records across the full fleet. Without that capability, recurring issues are addressed reactively, one event at a time, rather than being identified as systemic problems deserving a coordinated intervention.
