Abstract: Introduction was made to the noises sources of epoxy resin casting dry-type transformers. Analysis was made to noises estimation, noises measuring methods and their main reasons caused by noises. Combining with home-researched epoxy resin casting dry-type transformers with low noises, this paper raised the corresponding effective methods to reduce transformers noises, which provides references for the design of epoxy resin casting dry-type transformers with low noises.
Key words: resin casting; transformer noise; control; dry-type electric transformer
