If there are so many advantages to high efficiency transformers, why doesn every body use them?
Although it is proven that a transformer with NEMA TP-1 efficiency can save a great deal of energy and has a short return on investment but the lower first cost appeals more than future environmental and economical benefits to most of the contractors and building developers. The fact is that the end-uses will end up paying for the inefficiency of transformers and the utilities have to produce more electricity. We have to keep in mind that transformers use energy 24 hours a day, 7 days a week and 365 days a year for the whole of their life span, which is around 30 years. This means that any improvement on the efficiency of transformers will have significant impact on economy and environment. Many studies are done by the U.S. ORNL (Oak Ridges National Laboratory) in support of high efficiency transformers that are readily available to the public through their website www.ornl.gov Synergy Energy Inc. is doing its part by trying to inform the electrical consultants and the end-users about
