SEDA real-time substation equipment diagnosis
KEPCO reported preventing 17 equipment failures in 2025 with its SEDA diagnostic system
Problem
Periodic inspections could miss faults developing between visits. KEPCO needed to monitor aging power equipment with limited maintenance resources.
Approach
KEPCO introduced SEDA's real-time AI diagnosis in 2021. It combined sensor signals with equipment specifications and maintenance records to assess condition and prioritize work. In May 2026, KEPCO signed a technology transfer agreement with Germany's Maschinenfabrik Reinhausen; integration into the partner's platform remained planned.
Results
Takeaway
Condition assessments also informed replacement priorities. The disclosed prevented-failure count was KEPCO's own assessment.
