Transformer Core

Disadvantages of Amorphous Core Transformers

The brittleness property of amorphous metal has also make it un-friendly to the transformer manufacturers.

Due to small thickness and low saturation factor limitations present in making amorphous metals, larger core and consequently larger coils and tank size are required as compared to CRGO core transformers.

The amorphous metal saturates almost at 1.55 tesla whereas CRGO steel saturates at almost 2.03 tesla. Thus amorphous metal core-transformer results in increase of core size, conductor, tank and insulating oil.

Overall cost of amorphous core transformer is approximate 20 to 30 per cent costlier than conventional core transformers.
