Stepping Up With a New Step Down Transformer and Take a Load Off Your Electric Bill
It’s starting to catch on this energy efficiency stuff. For once, it seems, the numbers tell the story.
A man in Iowa buys a former manufacturing facility and changes it to a warehouse facility. He no longer needs the amount of power from the production days as the facility is now used to store portable generators. Building load is now mainly just for lighting. Starting in January 2007, the Federal Energy Policy Act of 2005 mandates new minimum energy efficiency standards for low voltage dry type transformers per the NEMA TP-1 2002 Standard.
The new owner swaps out the old 500 KVA dry type transformer which powered the building for a new Jefferson 150 KVA 480/240 dry type transformer at a purchase cost of $3,375.00. Given equal loads, the new Jefferson high efficiency 150 KVA transformer translates into substantial savings due to lower “no load core loss”. The new transformer saves up to approximately $175.00 per month in electricity used. The recovery cost break even point at that rate was 19 months. Another important factor when considering a new replacement transformer is the size of the transformer footprint. The new Jefferson had an 80% smaller footprint even though the transformer KVA capacity was reduced by 70%. These are numbers you can depend on. “Things are in the saddle…ride mankind ride.”
