Noise pollution of transformers becomes serious among rapid developing communities in modern cities. This paper reviews existing applicable measures of transformer noise control from three aspects: noise suppression of transformer itself, transmission path and transformer peripheral structures. It is indicated that the active noise reduction measure is a targeted noise reduction measure, while the system design and algorithm complexity make it not widely applied. It is also shown that designing a lightweight sound insulation material with high performance for the insulation layer of transformer is a more convenient and long-term noise reduction measure.
