Super low loss transformers are highly efficient transformers combining lower no load and copper losses.

Two types of losses exists in transformers, the first category are core losses, also known as ‘no load losses’. Core losses remain constant whether the transformer is fully loaded or not. That is why it is important to keep core losses to a minimum.

Using Amorphous metal core we can reduce those losses by up to 75% compared to conventional CRGO steel (see table below).

The second type of losses is copper loss, also known as ‘Load losses’. Copper losses vary depending on the load factor; these can be reduced in value by using higher cross sectional area of conductors in the windings, i.e. increasing the amount of winding conductor material.

The following table illustrates typical losses for different transformer types.

kVA	Amorphous core losses	copper losses	Total losses
1000kVA Amorphous	450W	7700W	8150W

kVA	CRGO core losses	copper losses	Total losses
1000kVA CRGO	1350W	12500W	13850W
1000kVA CRGO Low Loss	1070W	7700W	8770W
