The OPAL™ Design Best Practice for Retrofits

ESCO, Utility & Commercial Retrofit projects can expect 80% less losses when replacing pre 2007/TP1 transformer replacements, with E-Saver OPAL-R™ transformers.

There is more to a transformer retrofit than simply matching the capacity and input/output voltages with a typical transformer from the distributor’s warehouse. A transformer’s electrical characteristics affect fault levels, arc flash levels and inrush, which has much more impact in an electrical system than just efficiency.

In a retrofit, it is also important to consider site conditions like footprint and internal terminal layout. To address these needs, Powersmiths has developed a transformer design best practice called OPAL™ – Optimized Performance for the Application Load.

OPAL™ ensures compatibility by considering the system as a whole, which include goals like managing impedance, arc flash, fault level, inrush, harmonics, and more. OPAL is possible thanks to the tight feedback loop between design, onsite manufacturing, and extensive ongoing real world operating performance verification.

The result delivers the most savings per dollar spent.  Our flexible design and manufacturing process enables us to deliver solutions for the wide variety of site conditions and transformer manufacturers including footprint and internal terminal layout compatibility.
