Problems solved by technology

However, this detection method has the problem of poor real-time performance. Due to the large number of operating equipment in the power grid, the manual inspection workload through the ultraviolet imager is huge, and human observation is affected by the region, climate, experience and many other factors, so it is difficult to timely monitor the entire network. The risk of corona in live operation of equipment should be put forward in time for safety assessment. There is an urgent need for a real-time corona detection system for important power transmission and transformation equipment in the power grid. It has all-weather detection functions, timely early warning and alarm
