Abstract :
Various types of 3-phase core arrangements were analyzed with relation to the distortion of the flux, resulting from the separation of the total flux of each coil into two separate flux paths. The results show a large third-harmonic flux in each component, which increases the eddy-current loss and causes a high percentage of harmonics in the exciting current. In general, such cores might become objectionable from a telephone interference stand-point, and the increased losses are a disadvantage from a manufacturing stand-point.
