An expert system for acoustic diagnosis of power circuit breakers and on-load tap changers
作者：
Highlights：
• An expert system for acoustic diagnosis of OLTCs and CBs is proposed.
• The expert system can locate the cause of each anomaly in a broader spectrum.
• Acoustic signature features have been extraction in both time and frequency domains.
• Eminent speech processing techniques are utilized for feature extraction and comparison.
• Repeated testing of same device may assure the accurate diagnosis.
