Solutions for Noise and Vibration in Transformers

Noise and Vibration in Transformers are undesirable aspects of Transformer Operation. Noise causes disturbance in localities where the transformer is located. Vibration in transformers can affect other components connected to it. Sometimes, excessive vibration can cause components inside the transformer to come loose.

Methods of Noise Attenuation:

Location of a transformer plays a crucial part in the level of noise. A transformer located in a corner of a building with walls on three sides will have its noise amplified.

If the transformer is to be placed in a solid mass such as concrete which cannot vibrate, a solid mounting is preferred.

If the transformer is to be mounted on other surfaces such as a structural frame, a column or a platform, flexible mounting pads would be ideal

The construction of a Wall around the Transformer can help contain the transformer noise within a small area.

Use of Double Walls: Double Walls or limp walls are arrangements which contain two glass plates between which is a viscous liquid. The viscous liquid helps in damping the noise as it passes through.

A cheaper alternative would be the construction of a screening wall made of wood or concrete which can reduce the transformer noise.

Reducing Vibrations in Transformers.

Vibration pads can be used to alleviate the issue of vibration.

All the components inside the transformer should be rigidly fixed by using spacers.

All external connections such as cables, etc should be attached by means of flexible couplings.
