Effects of Degradation in Textolite Elements of Damaged Surge Arresters
The aim of this work was to investigate the effects of the currents flowing through surge arresters on the internal insulating textolite structure. The samples were removed from high-voltage arresters that were taken out of service due to malfunction or ...

Improved method for extracting resistive leakage current of surge protectors
The resistive leakage current in surge protectors is an important indicator to characterise its aging degree. It is of great significance to accurately extract the resistive components from the total leakage current for online monitoring of the surge ...
