Abstract Dry-Type Cast Resin Distribution Transformers (CRT) is the secondgeneration
of air-cooled distribution transformers where oil is replaced by resin
for electrical insulation. CRT transformers may installed indoor adjacent to or
near residential areas since they are clean and safe comparing to the conventional
transformers. But, as it is obvious, noise discrepancy is intrinsically accompanied
with all types of transformers and is inevitable for CRT transformers too. Minimization
of noise level caused by such these transformers has biological and ergonomic
importance. As it is known the core of transformers is the main source of
the noise generation. In this paper, experimental… More >
