Abstract
This paper presents the electromagnetic model for the 3- phase distribution transformer 250 KVA 11/.416KV core type. This model based upon using "ANSYS PROGRAM" to obtain the flux density distribution and losses, in this work, it has been change core material from silicon steel (Si.St.) to amorphous steel (Am. St.). Where, the iron losses reduction with 90%. The result for computer program are compared with practical measurements.
