Lightning damage is one of the main factors affecting the safety of power grid operation. Due to the low insulation level of the distribution network system and generally no lightning protection wire, lightning strikes are particularly prominent. At present, as the main means of lightning protection in distribution networks, lightning arresters are widely used in distribution lines and distribution transformers. In areas where lightning activities are relatively frequent, the failure rate of arresters has remained high. Faced with the large quantity and wide distribution of arresters, it brings huge manpower and economic pressure for power outage maintenance and troubleshooting. For this reason, our company has specially developed a lightning arrester working condition Internet of Things monitoring system.
