Amorphous Core Distribution Transformer
Due to its unique molecular structure, amorphous metal cores are more readily magnetized and de-magnetized than CRGO. This results in significantly lower power loss than CRGO. Also, the amorphous steel has lower hysteresis and eddy current loss resulting in very low No load current, energy and less heat, when compared with conventional CRGO core transformers. Switching to AMDTs reduce CO2 emission and fossil fuel consumption.
CRGO steel has exceptionally high mechanical elasticity and magnetic properties in the rolling direction. These crystals are often arranged by cold rolling at room temperature to coordinate the direction of grain formation in a specific direction. Since the magnetic properties during cold rolling depend on individual micro-crystals and direction of growth orientation.
C.R.G.O (Cold Rolled Grain Oriented) core is used in transformers to reduce eddy current losses and increase corrosion resistance. It also contributes to a reduction in coercive force resulting in a decrease in the loss of reverse magnetization in transformers.
