    Abstract
    A study was conducted using sinusoidal waveform to capture flux pattern in CRGO M5 material in a 1000kVA 11kV 3 phase transformer core. It is found that it takes about 180⁰ electrical degree cycle for a pool of flux to migrate from one core limb to the other two limb. The computed and experimental values at 1.7T flux density for the core losses had shown a difference of 4.2 %. There are two loops of flux flow exist at any phase( ωt) angle in the core. The hotspot area of the core is near the inner core of the T joint and along the core window. The 2D FEM software used has satisfied and fulfill the objective of the work interest.
