A corona noise is made due to the complaints about the corona noise from the inhabitant. occurrence of the partial discharge on the insulator. The The purpose of this research is to develop the system purpose of this research is to develop a monitoring to monitor the corona noise produced by the partial system of the corona noise. To develop the monitoring discharge with the insulator. We must establish the system, we must investigate the relationship between relationship between the corona noise and the polluted the corona noise leve
