Do you simply venture to your local electrical supplier and inquire for a transformer? You should rest assured to gain knowledge about the type of transformer you need along with its intended applications.
It would be essential to understanding that incorrect use of a transformer, similar to any electrical appliance could prove very dangerous. Let us understand the transformateur à sec, also known as cast resin transformer.
Understanding dry type transformer
The dry type transformers would be best described as power transformers. Their windings encased in epoxy resin would make the installation procedure relatively easier, as they would be dry and does not need cooling oil.
In addition, you do not require containing them in a fire-proof vault. The epoxy later would assist in protecting the transformer against corrosion and dust. The dry-type transformers would be used for a wide range of applications. It could be installed both indoors and outdoors.
Transformers have been used for increasing or decreasing currents and voltages in an electrical circuit. There have been a wide variety of transformers made available inclusive of liquid-type transformers. However, there would be several good reasons why a dry-type transformer has been recommended for use. These have been deemed economical, pack imperative safety features, and have been relatively more efficient in their functioning.
The dry-type transformers have been commonly used for utility, industrial, and commercial applications. These transformers would be able to withstand different weather conditions. Moreover, the dry-type transformers have been rated for outdoor use and would be mounted on a skid frame. However, these have not been the only reasons why a dry-type transformer has been a better option. Let us delve on more reasons for using dry-type transformers.
Reasons for using dry-type transformers
A dry-type transformer doe not entail any moving part. Therefore, it would be static using the environmental friendly temperature insulation systems. The term ‘dry’ would refer to the system being cooled through natural ventilation opposed to using silicone, oil, or liquid to cool coils through natural ventilation other than using the oil, liquid, or silicone for cooling the coils and the electrical core.
The dry transformer would be deemed as voltage changing. It implies that the air would be cooled rather than cooling the liquid. The dry transformers have been deemed relatively safer. As a result, these could be placed indoors. These could also be placed closer to loads. It would help make the entire system highly effective and efficient in its functionality.
