Abstract

The noise is major obstacle element in power line communication. However, because power supply networks are not designed for communication, there are various noise sources. Accordingly, a study of characteristic and cause of noise generated in low voltage transformer is important for outdoor power line communication. In this paper, we measure low voltage transformer noise in 1-30MHz using spectrum analyzer. We analyze cause and pattern of noise considering partial discharge.
