Compare the annual operating cost of two transformers and find the payback period of the lower-loss unit. Adjust loading and electricity price to update the results instantly.
Enter a price for both transformers to see the payback period and 5-year cost graph.
Annual operating cost reflects the cost of transformer losses only (no-load plus load losses at the selected loading), assumed energized 8,760 hours per year at the stated loss values, with no temperature correction and no adjustment for harmonic or additional stray losses. Energy and purchase prices are estimates entered by the user; actual costs and savings will vary.
