Abstract
The effect of the magnetic field distribution upon the iron losses of transformers is represented in practical formulas for the examples of core- and shell-type single-phase punching cores, and of the 3phase core-type core. This computation furnishes as much as 13.5 per cent lower core losses, as compared with previous conventional methods. In another application, it is shown that a widening of the yokes permits only a relatively small reduction in losses.Keywords
