Section 4 – Power Transformer Design

2011-8-6  core (other than in toroids) is near the transformer surface. Heat generated within the winding is distrib-uted from the surface to the internal core. Although copper has very low thermal resistance, electrical in-sulation and voids raises the R T within the winding. This is a design area where expertise and experience is very helpful.
