Transformer Efficiency Standards Proposed

Posted November 06, 2006 8:00 AM

The Edison Electric Institute says that there are about 40 million distribution transformers in the U.S., so even small efficiency improvements would save tremendous amounts of energy. Existing efficiency is about 98% and a new standard would increase this to between 98.73 and 99.36%, saving approximately 8.5 billion kilowatt hours of electricity per year.

I think this type of thing is what we HAVE to start doing in the world, finding ways of how to do what we HAVE to do more efficiently, energy harvesting, transduction wherever we possibly can....I think myself that any advances would be primarily in the WIRE ELEMENT itself, and then exactly how the transformers are designed...I am currently working on a totally new design for a totally different type of wire element, and also looking at a new transformer design, and right now I feel that any big breakthroughs are going to come from new wire element, the principles it works on and exactly how electrical interconnects are made, as opposed to transformer design breakthroughs. There are a lot of "exotic" materials out there, the devil is in the deatils, the trick is after the wire element is formulated exactly how does one make the manufacturing process mainstreamable and cost-effective??? This is just to encourage and give food for thought to anyone out there who may be looking at this type of thing, I have some valid ideas, but if I could give what I DO have at this point to better, brighter minds who are already in the field and better connected and let them run with it, so be it. It doesn't matter who gets the credit so much at this point as it matters in does the job get done. Good luck whoever....

Why are large high voltage and medium voltage transformers insulated with oil, and low voltage end user transformer dry-type? Dry type and Oil filled MV transformer price seem pretty closed. It would seem a highly automated mfg process could build a high effeciency LV oil filled transformer. Same kVA, a MV Xmfr is about double the price of a LV. But the MV had a more Heavy duty enclosure, MV Switches and fuses. The MV transformer has a 65 degree C rise, vs 80 degree at best for a dry type.

It just seems this might be a way of getting more effieciency out of our present methodes
