Abstract:

The U.S. Navy is investigating transformer alternatives to replace PCB transformers. Currently, NCEL is making a technical evaluation of various non PCB transformer replacement alternatives and determining the Life Cycle Costs LCC of these transformers. These include mineral oil, silicon oil, RTemp, amorphous core, vapor-cooled, ventilated dry, sealed dry, and cast coil at kVA ratings of 25, 75, 150, 300, 350, 500, 750, 1000, and 1500. Life cycle savings of amorphous core transformers over conventional silicon steel are also analyzed and show substantial savings. A 1500 kVA amorphous core transformer that is loaded at 90 percent and with a 15 percent price differential over a similar silicon steel transformer can produce life cycle savings of nearly 75, 000 with a payback of 2 to 3 years. For the purpose of transformer cost comparison, life cycle costs are composed of the purchase price, load and no- load costs. Life cycle costs are computed for the entire life cycle of 30 years. Energy costs of 0.06k Wh is used throughout this report with a compound growth rate of 5 percent over the assumed life cycle of 30 years for each transformer. jhd
