In this article we will discuss about the amorphous core transformer, explained with the help of a suitable diagram.
The role of a transformer is to convert high-voltage electricity supplied from a power station into lower-voltage electricity for safe use. Transformers operate 24 hours a day, seven days a week during which time they undergo constant losses of 2 to 4% of the electricity that passes through them.
This loss is divided into two different categories: load losses caused by the load on the transformer during the use of electricity and no-load losses (standby electricity) caused regardless of whether a load is present. Amorphous core transformers significantly reduce no-load losses by using an amorphous alloy for the iron core, which the transformer windings that carry the electricity are coiled.
The expected reduction in energy loss over conventional (Si Fe core) transformers is roughly around 70%, which is quite significant. By using an amorphous core – with unique physical and magnetic properties – these new type of transformers have increased efficiencies even at low loads – 98.5% efficiency at 35% load.
Electrical distribution transformers made with amorphous metal cores provide excellent opportunity to conserve energy right from the installation. Though these transformers are a little costlier than conventional iron core transformers, the overall benefit towards energy savings will compensate for the higher initial investment.
Amorphous core transformers reduce the impact on global environment. The countries like India and China having huge electrical grid and supply network has immense potential of energy savings by using amorphous core transformer. Both the countries along with other countries around the world are now-a-days going for energy efficient transformers such as amorphous core type transformers.
