Causes of Noise Generation & its Mitigation in Transformer

Abstract: This paper presents causes of noise generation in transformers and its mitigation. The ministry of environment has specified noise level for different areas i.e. industrial, commercial and residential. In this paper there are three causes of noise generation in transformer i.e. core sound, load sound and sound by cooling fans & pumps. Various methods are suggested in this paper in order to mitigate the sound in transformer
