Investigate the power losses for transformer design on different material of CRGO (Grain Oriented Material)

Abstract

The power loss will effect by the silicon contents on Grain Oriented Material. This will discuss about the core loss that occur in two different grain oriented material as M4 and M5 specimens. In this paper baby Epstein frame is optimized for both materials with flux density between 1T to 1.8T at frequency 50 Hz. The leakage flux was investigated during power loss measurement at the corner and limb. The losses that occur in M5 specimen is higher than the M4, it is because M5 have less silicon contents compare than M4.
