Article Title: An Overview on Amorphous Core Transformers
by Man Mohan

Abstract:
In this paper, an amorphous core transformer is highlighted. Configuration of amorphous C-core and its magnetisation characteristic (B-H) are described. Factors affecting the design are also discussed as a comparison with a conventional transformer. It is concluded that, advantages with amorphous core transformers are - low core losses, low magnetising current, less zero sequence current, less noise, higher efficiency and longer life; however the disadvantages are higher inrush current, more harmonic problem, bigger size and higher initial cost. The problem of third harmonic may be eliminated by adopting zig-zag connection in place of star connection. Purpose of this article is to provide a knowledge base about amorphous core transformers, to students of transformer design, by discussing some necessary issues.
Keywords: amorphous core, CRGO steel, distribution transformer, transformer design, core losses.
