In January 2007, the Energy Policy Act of 2005 (EPAct 2005) set the minimum
efficiency level (TP1) for transformers. While this standard sets a minimum
performance level, transformers rated at TP1 do not provide the greatest
efficiency or offer the lowest life cycle cost.
Acme POWERWISE C3 transformers are 30% better performing in efficiency
than standard TP1 transformers. Thanks to a more efficient core and higher-
grade electrical steel that minimizes losses, these energy-efficient units even
exceed the requirements of the US Department of Energy Candidate Standard
Level (CSL) 3 performance standard, commonly referred to as “C3.”
Depending on the kVA size, this increase in efficiency can save thousands of
dollars in energy costs per transformer. Whether you are looking to upgrade
your older pre-TP1 transformers or specify the highest-efficiency transformers
on your new project, Acme POWERWISE C3 transformers can deliver the
power and performance you need.
Within a typical facility, increasing the efficiency of your transformers can provide significant savings in a short period of time.
Payback usually occurs within 2.5 to 3.5 years, thanks in large part to our no-load losses. Because no-load losses are present
even when the transformers are lightly loaded, they are critical to overall efficiency — and POWERWISE losses are up to 40%
less than traditional TP1 designs.
EVALUATING TOTAL COST OF OWNERSHIP
Total Cost of Ownership = Initial Cost + Yearly Energy Cost
Cost over the life of the installation should be the most important factor when deciding which technology to use. Since the typical
transformer lasts 25 to 30 years, the total life cycle cost far outweighs the initial purchase price of the transformer. The electricity
wasted by low initial-cost transformers can amount to millions of wasted kilowatt hours over the operational life of the installation.
