Amorphous steel cores from freeamfva's blog
Amorphous Metal Distribution Transformers (AMDT) from ABB represent the ultra-low loss design solution, delivering the highest efficiencies. They are designed with a unique alloy whose structure
of metal atoms occurs in a random pattern and is used in lieu of conventional Regular Grain Oriented (RGO) silicon steel. RGO has an organized grain structure with much higher resistance to magnetization cycles, which leads to higher core losses.Get more news about Amorphous core,you can vist our website!
Amorphous metal – A technological advantage Amorphous metal (AM) enables a significant reduction in no-load losses as compared to RGO, up to 70 percent lower as noted in the table for representative liquid-filled transformer designs.
Studies have also shown benefits from AM in the presence of harmonics or integer multiples of the power frequency (50 or 60 Hz). When non-linear loads (eg, rotating machines) are present, they cause the current and voltage waveforms to distort, causing harmonics which increase losses in the transformer and reduce power quality. However, these harmonics losses are reduced in an AMDT. This translates into operating savings across a variety of resistive and inductive loads.
The much lower losses of the AMDT result in significant energy and monetary savings over the lifetime of the transformer.
Amorphous transformer manufacturers in India and other countries make these transformers by applying a special method to create the core. In the conventional transformers, the core is made up of metals. Metals get heated during the magnetization and demagnetization processes. As a result, a portion of the electric energy is wasted as heat energy. An amorphous metal core transformer has the core made up of some alloys. Amorphous transformer core materials are mixed together in molten stage and then are super cooled. The process is very similar to making glasses. So, the amorphous transformer manufacturers call the amorphous metal distribution transformer as the Metallic Glass Transformer as well. When the metals used for the core are crystalline, they produce more heat. With the specially made amorphous alloy distribution transformer, the core is not crystalline. This means, the transformer produces less heat during load. When the loss is super low, this type of transformer is called super low loss amorphous transformer.
The applications and advantages of an amorphous distribution transformer are ample. Amorphous iron transformer core has high magnetic susceptibility and high electrical resistance. Amorphous transformers in India are either imported or manufactured locally by amorphous core transformer manufacturers in India. These are made with a ferromagnetic amorphous metal as the core. The mixture of iron, silicon and boron give the core very low coercivity. The two kinds of losses are heavily reduced with an amorphous core transformer. When there is no load, the loss is called the no load loss. This is mainly due the core of the transformer heating up.
With the non-crystalline metal alloys, the loss is reduced to more than 70%. The other type of loss is called the copper loss; this is when the transformer is under heavy load. A typical amorphous core transformer (AMT) has less copper than the conventional transformers. Due to this fact, an AMT can have less efficiency at full load. To compensate this, more copper and core materials are added to making energy efficient AMTs. This is why they are expensive than the traditional ones. The bigger the size of the transformer, the more the copper windings are needed.These are used mainly in the grid distribution systems. There are some specialized electric motors that operate under high frequencies which would use these transformers as well. Rajasthan Powergen Transformer P. Ltd. is one of the leading amorphous core transformer manufacturers in India.
