Transformer Reliablity for Utilities & Municipalities
End-to-End Transformer Care for the Assets Your Community Depends On
Why Transformer Reliability Matters for Utilities
Utilities and municipal power providers carry a heavy responsibility: keeping power flowing to entire communities, often with aging fleets, constrained budgets, and a workforce that's retiring faster than it can be replaced. Few operations depend on transformer health as directly as a utility.
Several pressures are converging right now:
- Aging infrastructure and a retiring workforce. Many utility transformers are decades old, and the experienced staff who know them are leaving the workforce. That thins the in-house expertise needed to interpret diagnostics and plan maintenance.
- You can't rush a replacement. Power transformer lead times can now stretch well past two years, with prices up more than 70% from pre-pandemic numbers. Extending the life of the fleet you already own is a business-critical strategy, not just a cost saver.
- Reactive repair is the expensive default. Fixing assets only after they fail costs an estimated 3 to 10 times more than planned, proactive repair—before counting the outage itself.
The path forward is a proactive, data-driven program. Most utilities believe in this mindset, but what they need is a partner like SDMyers who supplies the expertise their internal teams can't scale.

Frequently Asked Questions
Best practice ties testing cadence and intervals to each transformer's type, loading, environment, and criticality. Generally, routine visual inspections, annual oil analysis, thermal imaging, and partial discharge inspections are more frequent for the most critical assets.
SDMyers maintains the history and diagnostic record of your fleet, so institutional knowledge stays intact through any and all staff transitions. Our diagnostics team is like having transformer experts on staff who provide the interpretation your internal team may no longer have in-house.
Yes. With NFPA 70B now an enforceable standard, we help you build maintenance records that hold up to audits and satisfy compliance requirements. NFPA 70B now requires a documented electrical maintenance program (EMP), including annual infrared scanning. We help you build and document a compliant, defensible program.
Most operations aren't short on data. They're short on confident interpretation. Our diagnostics team translates test results into clear, prioritized recommendations, backed by the world's largest transformer fluid analysis database. You'll know what the data means and what to do about it.
