Abstract
There are core materials which are strong in anisotropy and others that are weak. The strong anisotropic materials, grain oriented silicon steels, are suitable for miter joint cores, while the weak anisotropic materials, including wrought iron, nongrain oriented silicon steels, and amorphous metal, are suitable for the H-I plate core, the E-I plate core, the L-plate core, and the I-plate core. The traditional core designs were developed when operating transformers at high inductions. However, the current trend is to achieve low loss at lower inductions. Core losses improve as steel gauges decrease and grades improve. Lamination geometries greatly affect core compactness and core performance.
