Abstract

This paper discussed result of an investigation towards the effect of using two different Cold Rolled Grain-Oriented (CRGO) Silicon Iron material to the 100kVA three phase distribution transformer. This experiment used M4 and M5 material with 5mm different overlap length, configured with yoke and limb arrangement. Power loss has been measured using no-load test with 15 layer of lamination. The power loss of the transformer model core of M4 material at the operation mode flux density, 1.5T is 0.976W/Kg. This shows that M4 material have lower overall power loss compare to M5 material where M5 material have 1.060W/Kg overall power loss during operation mode.
