In this paper the results of audible noise measurements to ten no-load distribution transformers are presented using the sound pressure method. The tests were done in the Audible Noise Laboratory of Universidad del Valle, according to the requirements described in the Colombian Technical Standard NTC 5979. The tests allowed to verify the conformity of the product in respect with the audible noise limits established in the Colombian Technical Standard NCT 5978. In addition, it was possible to identify the effect of noise emissions of two transformers when making variations of voltage in the power source. It was found that the noise level emitted by the transformers under test is considerably lower than the limits established in the standard ...
