Energy-Efficient Transformer: What is it?

Energy efficient transformers use highly conductive materials to reduce power loss during energy transfer. Traditional transformers lose 40-50% of power, while energy efficient transformers only lose 20-25%. Conductive materials like amorphous metal improve power transfer and reduce carbon dioxide emissions.

A transformer is an electrical device that transfers electrical energy from one electrical circuit to another. While ordinary transformers cost a significant amount in power loss to a line, resulting in about 40-50 percent of all transmission and distribution losses, an energy efficient transformer is designed to be more efficient and reduce the amount of power loss that occurs when energy is transferred. An energy efficient transformer accomplishes this by using highly conductive materials, including electrical steel and easily magnetized materials.

Transmission and distribution losses are some of the biggest enemies of efficient power transfer in transformers. These losses are natural friction losses that occur as electricity moves through the line. Just like dragging a cloth along a piece of sandpaper, where tiny portions of the cloth will become entangled in the process, some of the power flowing through a transformer is similarly “entangled” and displaced by the substances through which it moves. The amount of “entanglement” that occurs depends largely on the conductivity of the materials through which the electricity flows; highly conductive materials can pass a charge with much less entangling effect.

The effectiveness of a modern energy-efficient transformer is about twice that of a comparable 1970s transformer. This means that while an average transformer causes a 40 to 50 percent power loss—in other words, only half of the power moving through the transformer actually gets to the next circuit—the power retention of a point-of-efficient transformer energy view is much higher, suffering only 20-25 percent loss. Much of the power loss in traditional transformers comes from the substances used in their creation; standard steel and other ordinary metals tend to impede the flow of electricity to the point that much of the power is lost through heat conversion.

A modern energy efficient transformer solves this problem through its conductive materials of construction. When created with materials that have higher conductivity, such as steel specifically designed to hold an electrical charge, energy-efficient transformers retain more of their original power, allowing more of it to be channeled into the adjacent circuit. An amorphous metal transformer is a good example of this; The core of the transformer is made of material that can be easily magnetized and demagnetized, resulting in not only better power transfer, but reduced carbon dioxide transmissions when generating power from fossil fuels.
