Dry-type transformers are widely used in various industrial and commercial applications due to their numerous advantages. One major concern, however, is the noise they produce during operation. The noise level can vary depending on the transformer's size, design, and load conditions.

There are several reasons why dry-type transformers produce noise. The primary source is the magnetostriction effect, which causes the transformer core to vibrate and generate noise as it is magnetized and demagnetized. Other sources include vibrations from the windings and structural components, as well as the cooling system.

To mitigate the noise level, various noise reduction techniques can be employed. One common method is to use sound barriers or enclosures around the transformer to absorb the noise. These enclosures can be made of different materials such as concrete, metal, or sound-absorbing panels, depending on the application requirements.

Another effective technique is to use vibration isolation systems that reduce the transfer of vibration and noise from the transformer to the surrounding structure. These systems use vibration isolators made of rubber or other materials to separate the transformer from the floor or other components.

In addition to these techniques, there are other measures that can be taken to reduce the noise level of dry-type transformers. These include improving the design of the transformer to minimize core and winding vibrations, using low-noise cooling systems, and optimizing the transformer's load conditions.

Overall, the noise produced by dry-type transformers can be a significant concern for many applications. However, with proper noise reduction techniques and maintenance, the noise level can be effectively controlled, making these transformers a viable option for a wide range of applications.
