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 engineering considerations for a transformer upgrade include precise load analysis, lifecycle cost assessment, selecting the right type (oil vs. dry), ensuring installation compatibility, and planning for future maintenance. A holistic approach ensures reliability and cost-effectiveness […]

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 growth, and long procurement lead times that turn a small problem into a multi-year headache. Replace (not reinforce) when the unit shows irreversible insulation aging, repeat internal fault behavior, lost thermal margin, or when the […]
