INTRINSIC DEFECTS IN ZnO VARISTOR CERAMICS

open access: yesActa Physica Sinica, 1996
The relationship between dielectric loss factor D (tanδ) and frequency for ZnO-Sb2O3-BaO and ZnO-Bi2O3-Sb2O3-BaO varistor ceramics has been investigated. A new dielectric loss peak was found near by 2MHz at room temperature for the sample in the absence of Bi2O3, the corresponding electron trapping level was about 0.18 eV, it was considered that the ...

Detection of failures in HV surge arrester using chaos pattern with deep learning neural network

open access: yesIET Science, Measurement &Technology, Volume 18, Issue 9, Page 603-615, November 2024.
This paper proposes a fault diagnosis method for HV surge arresters based on the chaotic system and CNN. Compared to AlexNet, HOG+BPNN, HOG+SVM, HOG+DT, and HOG+KNN detection methods, the accuracy of the method proposed in this paper is 97%. Abstract As a protective component of HV equipment, the primary function of a surge arrester is to mitigate the ...
