What is the approximate percentage reduction in core losses for distribution transformers built with an amorphous core compared to those with a laminated steel core?

The choice indicating a 60 percent reduction in core losses for distribution transformers built with an amorphous core is based on the unique properties of amorphous materials. Amorphous cores are manufactured from a non-crystalline structure that allows for lower magnetic hysteresis losses compared to laminated steel cores.

When electricity passes through a transformer, energy is lost primarily due to the magnetic properties of the core material. Laminated steel cores can cause significant hysteresis losses due to their crystalline structure, which results in energy dissipation as heat during the magnetic cycles. In contrast, the non-crystalline structure of an amorphous core minimizes this effect, leading to approximately 60 percent reduction in core losses.

This characteristic makes amorphous core transformers more efficient, reducing operational costs related to energy losses and making them a more environmentally friendly option. Through improved material technology, these transformers represent a significant advancement over traditional laminated designs, which explains the declared percentage reduction in core losses.
