Simulation of flux distribution and loss calculation at three-phase transformer core with the mix 60o-45o T-joint

Abstract

This paper describes the result of simulation of flux distribution on 100kVA 3phase distribution transformer assembled with 23o T-joint and mitred lap corner joint with stagger yoke and limb for one lamination. The simulation involves the variation of flux. The flux distributions have been simulated using 2DFEM by Quickfield Software built from M5 (CGO) grades material of transformer core laminations. The flux density is 1.78 T maximum at the centre limb of transformer core and the loss calculation is 2.54 W/kg.
