Complete Guide to Transformer Retrofits

Complete Guide to Transformer Retrofits

February 18, 2026

Every facility has a unique electrical setup. Even sites that use the same transformer model have different connection configurations, mounting arrangements and bus work. When your transformer fails or you need an upgrade, waiting months for a custom-built replacement could cost you thousands in downtime. Transformer retrofits offer a faster solution. These modifications involve adapting stock […]

How to Navigate Transformer Lead Times

How to Navigate Transformer Lead Times

February 4, 2026

Reliable power keeps facilities operational, protects critical equipment and ensures essential services remain uninterrupted. Transformers help maintain that stability by converting primary power to usable voltages that systems can safely utilize. When a unit fails, operations can come to a halt until a replacement transformer arrives. The current lead time for a custom dry type transformer often […]

Why Do Transformers Hum? Understanding Transformer Noise

December 30, 2025

Loud equipment is often a nuisance, but it can also be a safety issue if it contributes to excessive noise levels. Transformers often hum or buzz, but it usually doesn’t mean anything is wrong with them. Humming can be a sign of normal operations and magnetic forces at work. Still, too much transformer noise can […]

The Critical Role of Transformer Maintenance in Industrial Operations

December 9, 2025

Many businesses and organizations take transformers for granted until a performance issue arises or they break down unexpectedly. Some maintenance teams only take action when a visible problem occurs, overlooking the day-to-day inspections that help identify minor issues before they worsen. These oversights create long-term vulnerabilities that a proper maintenance strategy can help eliminate. The […]
