Abstract

Recently, demands for the reduction of noise generated by transformers have been increasing. Accordingly the noise of transformer occasion displeasing to residents therefore the transformer needs to decrease of noise. One method of reduction such a noise is to build a free-standing enclosure of concrete and steel plates around the transformer, however, this method has some disadvantages, for example, a lage area is needed for equipment installation. In the paper, the vibration and noise effect which is transferred from reinforce channel to insulation panel generated by transformer have been identified for the several kinds of insulation panel and damping sheet experimentally.
