- •
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.
