A transformer is static equipment whose main purpose is to transform power from one circuit to another. The machine has no moving components and this is why it is known as static equipment.

It primarily works on the principle of mutual induction, therefore doesn’t change frequency during the process. It can be classified in different ways, which completely depends on their use, design, purpose and need of your industry. Some of these common types are as follows:

• Special purpose transformer

• Auto transformer

• Rectifier transformer

• Control transformer

• Three phase transformer

• Step down transformer

It is vital for you to know that it doesn’t generate power. Rather, it transfers electrical power from one AC circuit to another magnetic coupling. The core a vital part of the device provides a controlled path for the magnetic flux generated by the current flowing through the windings. Common components of the devices are Core, Winding, Output connection and Input connection.

The main function of the transformer is to transform high voltage of AC ...
... power to lower voltage without damaging the frequency level. It is one of the fascinating inventions that drive power to our offices or homes. After knowing everything about the device, now the major issue that irritates the people is why do they hum?

Fundamentally, the transformer sound is caused by a phenomenon which origins a price of magnetic sheet to extend itself when magnetized. The main reason behind that humming sound in the equipment is magnetostriction effects. This Magnetostriction effect is a property of the ferromagnetic materials and whenever it comes in contact with a varying magnetic field, it changes their dimension creating vibrations, which is the main reason of hum sound in the transformer. The procedure can’t be stopped so the question is how to eradicate the noise. No worries, the solution to the issue is simple. Just have a look.

• You can utilize oil barriers to eradicating the humming sound as it assists in insulating the vibration sound, which automatically lessens or eradicate the humming sound.

• Another way to lessen hum noise is by using right material and design while constructing the walls of the transformer tanks.

Soundproof door curtain installation

Integrating the casing in this way implies that a soundproof door curtain not only keeps away noise, but also prevents hot or cold air from entering your home and causing high cooling and heating costs. A serene home can save money from the same soundproof room.

The best thing about a sound screen is its simplicity of installation. A soundproof window is positioned in back of your existing window, and can be shut and opened in the same way. There will be no labor costs involved for taking out your present windows.
