Founded in 1902, Square D established itself as a leader in power distribution equipment before being acquired by Schneider Electric in 1991. Square D’s EX series and Premium 30 transformers have served commercial and industrial facilities across North America for decades. Despite their high durability, many of these units installed during the 1990s and early 2000s now approach the end of their effective service life.
When you need to replace your Square D unit, ELSCO offers several cost-effective solutions that work with your existing wiring and infrastructure.
Why Would You Need to Replace Your Square D Dry Type Transformer?
Various signs suggest your Square D transformer may have reached the end of its lifespan, including:
- Overheating: Rust on metal components, carbonization on the windings and loose connections indicate possible overheating.
- Increased energy consumption: Your monthly utility bills show unexpected increases without changes in your operation.
- Vibration and noise: Your transformer produces loud humming sounds or excessive vibrations compared to when you first installed it.
- Discoloration: The unit’s exterior shows signs of overheating, including discolored insulation near the top of the coils.
- Repeated breaker trips: Overloading, faulty connections and damaged wiring can all contribute to the breaker tripping.
Identifying these warning signs early allows you to plan your replacement rather than responding to a sudden failure, saving you money while preventing unnecessary downtime.
ELSCO's Square D Transformer Replacements and Retrofits
When replacing a Square D transformer, facility managers and business owners have two options: standard replacement stock units or engineered retrofits. Traditional replacements rarely match the footprint and connection points of older Square D models, especially their distinctive bus bar arrangements and ventilation systems. This incompatibility often involves modifying the transformer or your facility, resulting in extended downtime and additional installation costs.
ELSCO’s retrofit transformers solve these challenges with a plug-and-play unit that fits your existing electrical connections. Our engineers consider the old unit’s mounting configurations, terminal arrangements and operating parameters to modify an in-stock transformer and create a solution that meets your operational needs while saving time and money.
