Simple, Yet Effective Techniques To Reduce Transformer Noise

A transformer is an electronic device made of stainless steel windings and cores and performs the function of supplying power from one source to another through electromagnetic induction. The device is very useful in commercial as well as industrial sectors and more and more people switch to the technology for better power supply. Though, the device in some cases creates a lot of noise that can be harmful to the users and the device itself. Therefore, it is important to take some serious actions to get rid of the transformer noise, but before you hit the head and looking for a way, it is important for you to understand what the main cause behind such noise is. Identifying the main cause helps you solve the problem more efficiently and effectively. So, what are you waiting for? Just scroll down to get the answer to your query.

Basically, There Are Two Major Causes Of The Transformer Noise Such As:

  • Magnetostriction: It is basically a property of ferromagnetic materials that leads them to extract or contract their shape or dimension during the magnetization, which may create vibration in the device that automatically leads to transformer noise. You can simply control the Magnetostriction by the transformer design, so, you have to be very particular while making the choice of its type, model, and size.
  • Mechanical Abrasion: Another major reason of transformer noise is Mechanical Abrasion. Any sort of force and stress on the device creates vibration. Any vibration comes from the core is transferred to anything else attached to it that may cause the transformer noise.

Simple Techniques To Fix The Issue:

  • Reducing flux density can be very helpful in eliminating the transformer noise. Though, it is an expensive method because for reducing flux density you have to increase the amount of stainless steel in the core that requires investment.
  • Don’t worry, if your budget doesn’t allow you to pick the above technique, so you can go for another option that is the use of suitable adhesive to minimize the vibration that automatically reduces transformer noise. Putting adhesive between lamination layers is not so expensive and delivers you the effective and expected results. But you have to be sure that sheets are free from any contamination and also don’t have any oil scum.

These simple tricks and techniques help you get rid of transformer noise and all of are very easy to adopt. But make sure you consult an expert before picking any of the techniques as the method can be varied as per the model of your device.
