Power distribution equipment is crucial to the operation of smart grids. Through the combined use of communication, IT and modern management technologies, the equipment can greatly enhance the utilization of power devices and reduce power loss to put power grids on the path to more economical and efficient operations. The use of advanced remote sensing and measuring technologies, equipment, control methods and decision-making support systems can put power grids on the path to the reliable, safe, economical, efficient and environmentally friendly operations. The equipment can integrate, share and employ real-time and non-real time information to provide complete and exquisite graphs showing operational status. Meantime, it can provide corresponding decision-assistant support, implementation control plan and response plan. The establishment of two-way interactive service pattern enables customers to be aware of real-time electricity capacity, power quality and early warning of failure, so as to better arrange the distribution of electricity use and comprehensively improve intelligent level.
