Myths Related To Amorphous Transformers

Amorphous transformers are made of high degree alloys of metal with unstructured order, and thus the metal used in its formation is also referred to as” The Metallic Glass.” In this blog, we will be acknowledging the myths relates to Amorphous transformers.

Cannot sustain higher current voltage:

One of the biggest misconceptions about amorphous transformers is that it can’t withstand higher current-voltage above 250KVA and thus is limited for use in low output and single-phase appliances only. However, this is completely false, since it has passed a test which clearly reveals that it is safe to be used in higher voltage situations, and works better than conventional transformers.

Material Width Availability limitation:

 It is assumed that since amorphous steel sheets are available in three widths, it will restrict the design products as per the distinct customer needs and in fact, it will impose unpredictable pricing. However, it is true that the amorphous material comes in only three widths,  but the amorphous transformer suppliers in Delhi explains that it can still produce the design according to varying needs of the client by altering the number of core stacks, and it’s thickness. Moreover, due to the availability of numerous suppliers, and the expiration of the amorphous patent, the prices are quite stable.

Intrinsic Flimsy Amorphous Material:

Another myth that should be busted is that the usage of amorphous material is considered to be very fragile. So it’s assumed that if it bents more than it’s limit it will burst in fragments thus sheet splinters cannot be produced. However, we know that the material is very thin, but in amorphous transformers, splinters are produced during the manufacturing process by following a predetermined procedure.

Constant Loss for the No-Load Loss using Amorphous Core Material:

Since amorphous core materials are not majorly used, it is suspected that material remaining constant throughout the life expectancy of the transformer is unknown, unlike conventional silicon steel material. Perhaps, it is just a misconception because amorphous transformers present consistent no-load losses over the lifetime. Furthermore, it has been proven by conducting various studies as well.

Why hasn’t amorphous steel been used previously?

MYTH: It is believed that European manufacturers didn’t use amorphous core material even when it was available for more than 30 years due to the restricted application of this material. However, the reality is that earlier awareness regarding global warming and greenhouse effects we’re not considered significant as it’s today. Perhaps, now due to daily awareness on environmental subjects amorphous material is highly used and it is an alternative to CRGO transformers. Moreover, amorphous core transformers manufacturer claims that amorphous material is utilised to reduce the no-load losses which were higher in traditional CRGO transformers. Hence, it results in saving energy significantly.

Manufacturing restriction using Amorphous Core Material:

The last myth associated with amorphous core material is that during the manufacturing process, splinters tend to stick as amorphous steel is just 20-25 microns. Moreover, splinters can’t be removed easily and may further contaminate the fluid and actual windings. As a result, windings will not function anymore. However, to support this argument it should be acknowledged that splinters exist in the overlapping areas in amorphous transformers. The leading amorphous transformer manufacturer asserts that during the manufacturing process, this overlapping region is put under a chip like structure. Consequently, any core splinters that will be formed will be gathered in this chip like structure and hence won’t contaminate the oil.
