Partial discharge. XXI. Acoustic emission based PD source location in transformers
IEEE Electrical Insulation Magazine, 1995Acoustic emission-based partial discharge source location has been applied successfully to power transformers in both factory and field environments, and this method is becoming an established test procedure with a high success rate. With the aid of local utilities and utility laboratories that use acoustic emission apparatus daily, we expect further ...

Detecting and Monitoring Insulation Failure: A Review of Partial Discharge (PD) Detection Techniques
International Journal of Advances in Engineering and ManagementThe reliability and efficiency of electrical systems vitally depend on electrical insulation to prevent electricity leakage during transmission. However, due to various operational and environmental factors such as humidity, thermal stress, and others, insulation materials degrade over time. Therefore, detecting and monitoring insulation degradation at

A Novel Signal Extraction Technique for Online Partial Discharge (PD) Measurement of Transformers
2016One of the major difficulties of online partial discharge (PD) measurement of transformers is the effective extraction of PD signals, which are heavily coupled with noise. Wavelet transform has been widely adopted for the extraction of PD signals. However, its performance is highly dependent on proper selection of mother wavelet, decomposition levels ...
