    Autotransformer winding resistance calculator

    Calculate voltage ratios, power ratings, and efficiency of autotransformers. Features copper loss analysis, VA rating computation, and transformation ratio calculations for optimal design. An autotransformer works differently—only one winding is used for both the primary and secondary sides, resulting in better efficiency and a saving in size over two-winding transformers. With our calculator, engineers can find information about the transformation ratio, copper losses, and the VA rating of their equipment. Examining the regulation of voltage, core losses, and winding resistance allows you to make the best autotransformer design for various uses like regulation and power distribution, saving you money thanks to less wasteful use of materials.
