Electrical Engineering ⇒ Topic : Noise reduces by following methods

The noise emission may be reduced by the following methods/means

• Prevention of vibration of core-plate by the use of a lower flux density and giving attention to constructional feature (such as clamping bolts, proportions and dimensions of the 'steps' in plate width, tightness of clamping and uniformity of plates).
• Using cushions, padding, or oil barriers to sound insulate the transformer from tank.
• Designing suitably the tank and stiffeners to check tank wall vibration.
• Sound insulating the tank from the ground or surrounding air.

However, the noise problem cannot be solved completely
