ABSTRACT

Ceramic insulators may experience a decrease in internal insulation performance and become zero value insulators due to environmental factors after being put into operation. Regular zero value testing is required to identify zero value insulators. The impulse high voltage method is one of the effective methods for zero value detection, but existing impulse high voltage methods only focus on the voltage response characteristics of insulators under impulse high voltage, without paying attention to the current response characteristics. This study proposes a zero value detection method based on the current response characteristics under impulse high voltage. The response current is converted into an induced voltage signal through a magnetic ring inductor, and the difference between zero value and the peak induced voltage of a normal insulator is used to achieve reliable identification of zero value. In the case of insulator surface contamination, this method is more robust and has a lower risk of misjudgment compared to detection methods based on voltage response characteristics. The research provides new ideas for insulation testing of ceramic insulators, which helps to improve the reliability of the power grid. Further exploration is needed in the future to determine the reasons for the reliability differences between the two methods.
