Tips to Minimize the Buzzing Noise of Instrument Transformer Equipment

 Humming and buzzing sounds are commonly heard from transformers. The main cause behind the noise is magnetstriction. It is a process in which a magnetic steel sheet changes its dimensions or shape when magnetized. Again, when the magnetization is taken away it goes back to its original shape. The sound it generates might be controlled to some extent but cannot be completely removed. It is a vibrating sound that imitates the sound produced by generators and motors.

Here are some of the precautions that you can take while installing and mounting instrument transformer equipment, to reduce the humming noise.

 

Choose low traffic area for installation

If the transformer is installed in a high traffic area, the sound becomes annoying to people, especially if the surrounding noise is lower than the unit’s sound level. That is why it is advised to maintain at least one low traffic area between the transformer and high traffic spaces in commercial or residential buildings etc.

 

Corridors, corners, and stairwells should be avoided

The corridors, places near the ceiling are the places which increase noise and that is why installing a transformer in such places is certainly not a good idea. Similarly, the corners of a room also louden sound.

 

Install the transformer on a solid plane

Transformers should always be installed on heavy and dense surfaces like concrete walls or floors. Because plywood surfaces or thin curtain walls accelerate the humming sound making it intolerable. Mounting surfaces should be ten times heavier than the transformer itself.

 

Tighten the bolts enclosures

Make sure that the screws and bolts on the transformer’s cover and top have been tightened properly. Loose parts will vibrate when the transformer is working and this will automatically increase the noise.

 

Use oil barriers

Using oil barriers and cushion padding might help reduce the sound and control it from spreading. Though these are not capable to reduce the vibrating sound themselves but they reduce the frustration it causes among people staying in nearby areas.

 

Stick to a flexible installing method

Using additional dampeners along with flexible installing method and connection is highly recommended while installing these transformers on ceilings, walls, or frames. This will stop metal contact between the mounting surface and the transformer, to control sound transmission.

 

Apart from these above-mentioned techniques, you can always opt for the new and advanced technology, designs, materials, and installation method when you are planning to install a transformer. These days, stiffeners and other materials are used in transformer tanks to decrease the operating sound. So do not overlook the modern solution before finalizing the project.
