Last quarter, I audited a facility spending $450,000 annually on "preventive" maintenance. The shocking truth? 70% of those activities were actually reducing transformer life.
Modern maintenance strategies combine AI-driven monitoring, self-healing materials, and precise intervention timing. This approach reduces lifetime costs by 59% while extending service life by 40%.
Let me share insights from analyzing maintenance data across 1000+ dry transformer installations.
Why Do Traditional Maintenance Schedules Destroy ROI?
After reviewing 15 years of maintenance records, I discovered that scheduled interventions often triggered premature failures, costing millions in unnecessary repairs.
Traditional time-based maintenance ignores actual equipment condition and often introduces new failure modes. Modern approaches must prioritize data-driven decisions.
