By utilizing IoT sensing technology,real-time tracking and collection of electrical equipment current intensity,voltage level,and temperature changes data were conducted. Based on this data,a substation electrical equipment operation monitoring model was established,and decision tree algorithm was used to analyze and predict equipment status. All-weather monitoring can quickly identify and trigger fault warnings. The results show that using IoT sensing technology to all-weather monitoring the operation of electrical equipment in substations,the average fault positive rate of the three test groups is 90.78％,which has certain accuracy and practicality.
