Abstract :
Extra losses in shell-form power transformers are calculated. Some analytical methods are proposed for the calculation of eddy-current losses, circulating-current losses, and transpositions. Based on these methods a code has been written. Some calculation and test results are reported for a 13.333-MVA single-phase shell-form power transformer built for this study
