Technical Notes & Insights
Practical notes on power and distribution transformers, focused on selection thinking, engineering fundamentals, and project preparation.
Updated based on engineering experience and practical project discussions.
When preparing transformer specifications or reviewing technical requirements, it's common to encounter questions like:
- How should transformer capacity be evaluated in early-stage selection?
- Which technical parameters actually matter before sending an RFQ?
- What do IEC or ANSI requirements usually imply in practice?
- Which design or operating factors are often overlooked?
- What information should be confirmed to avoid rework later?
The articles below are written to help clarify these questions before project decisions are made.

What Are the Key Engineering Considerations for Upgrading Distribution Transformers?
Upgrading your transformers seems simple, but a wrong move can cause costly downtime and inefficiencies. This guide prevents that. Key...
When Should Distribution Transformers Be Replaced Instead of Reinforced?
If your distribution transformer is aging, the risk is not just failure. It is unplanned outages, safety exposure, missed capacity...
Blown Transformer: What Causes It, What It Looks Like, and How Long It Takes to Fix?
A blown transformer can sound like a gunshot, throw a bright flash, and leave you in the dark. The danger...
Why Is China Still the Best Country to Source Distribution Transformers in 2026?
Transformer lead times keep stretching, and projects miss energization dates. When that happens, I pay liquidated damages, and I lose...
Why do transformers matter in the real power grid?
Power feels simple until voltage has to travel hundreds of miles. Then losses rise, outages happen, and equipment fails. A...
