Amorphous transformer can be developed and produced by QTC manufacturer in Thailand, which is environmentally friendly transformer. The Amorphous Transformer can save the energy and having a very high efﬁciency at AAA0-AK level (En 50588-1:2017), thus this can reduce the Greenhouse gas emissions from electricity generating.

The Amorphous Transformer is the best solution to reduce electric energy loss. The Amorphous Transformer which will change the magnetic core material from Silicon Steel to Amorphous Alloy, can reduce the exciting current, and the No-Load Losses (NLL) by up to 80% ,comparing with Silicon Steel.

QTC Energy PLC is a ﬁrst company in Thailand, who can be capable of design and manufacturing for Amorphous Transformer, MEA and PEA speciﬁcation will be complied as well .

Amorphous Alloy is a general term for a metal with a non-crystalline structure of atom. Internal structure of the material has disordered. In transformers with amorphous cores, a ribbon of amorphous alloy is wound forming the core. The big beneﬁt of amorphous transformer is that amorphous alloy has lower hysteresis losses. In addition, Eddy current loss is decreased as the thickness is approximate 25 μm, which is about 1/10 comparing with silicon steel. Therefore, the No-Load Loss (Eddy current Loss and hysteresis loss) can be decreased to about 1/3 of silicon steel.

When applying magnetic field, random atomic structure leads less friction than Silicon Steel. Therefore it is easy for Amorphous Alloy to magnetize and demagnetize resulting in low Hysteresis Loss..

1. No-Load Losses (NLL) is lower than Silicon Steel Hysteresis Loss

Amorphous Alloy has very thin laminations (25 micron). Thin laminations result in lower eddy current loss as compared to Silicon Steel. Eddy Current Loss

Beneﬁt of AMDT

Concept of Total Owning Cost ( TOC )

2

Distribution Transformer usually can be operated >20-30 years (average lifetime in EU will be around 40 years).

TOC takes account of initial price and

running cost in a life time. not only initial price. TOC is suitable for economic analysisof energy efﬁcient and long life products. Purchase of Distribution Transformer

based on initial price is not economical in their life time.

Price of energy efﬁciency product such as AMDT is usually higher than Cold Rolled Grain Oriented Distribution Transformer (CRGO-DT) but running cost will be lower than CRGO-DT.

TOC = Initial Purchase Price + Cost of Future Energy Loss.
