The Statistics Method Application in Acoustics Vibration Detecting Post Insulators

Abstract

Acoustics vibration detection is detected the displacement of post insulator by inspection the change of vibration state. Hoe to indentify the situation of insulator accurately from vibration signal is fate for acoustics vibration detection. According to analyzing the vibration date with statistics method, it is proved that the vibration frequency distribution of the same type of insulator follow normal distribution. Based on this conclusion, the identification frequency section has been set for identifying breached insulators.
