Transformer Audio Noise Problems on an Eectric Power System

Since the end of the war, increased load demands, together with the location of housing developments in the vicinity of the power station, tend to make the electric power company more susceptible to noise complaints than ever before. Power companies which had not been concerned with the noise problem in the past now have become involved. The various factors of noise are covered and explained insofar as they apply to a transformer, one of the most common sources of noise. It is hoped that the review and discussion of the problems which exist may be of value to those interested in transformer noise, particularly to the transformer manufacturers and those responsible for transformer noise standards. The experience andelews of others, which have been reported elsewhere, are discussed, and a list of references is given for those who care to go into the problem in more detail.
