Background technique [0002] In the high-voltage power grid, the zinc oxide arrester is a protective device to protect electrical equipment from overvoltage. At present, it is considered that a relatively effective measurement method that can quickly and correctly reflect the internal quality problems of zinc oxide arresters is to measure the resistive component of the arrester, which is referred to as the resistive current discrimination method. The current monitoring method of arrester leakage current relies on manual on-site polling, the response speed is slow, and the detection accuracy is poor. Therefore, a new method is needed for the monitoring of a...

AI Technical Summary

Problems solved by technology

The current monitoring method of arrester leakage current relies on manual on-site polling, the response speed is slow, and the detection accuracy is poor. Therefore, a new method is needed for the monitoring of arrester leakage current in the high-voltage power grid system, such as using the bus and Automatic remote monitoring method of network technology

However, because the implementation of these automatic remote monitoring methods requires a stable and continuous power supply, and the implementation of conventional power supply systems cannot be allowed under the high-voltage power grid, solving the power supply system is a prerequisite for the realization of automatic remote monitoring methods
