Along with the development of science and technology, power companies are gradually applying many achievements of electronics, information, computer, control technologies, etc to modernize the power grid. Power distribution grids have a great impact on the customer’s power quality and business performance, so distribution substations and intermediate lowvoltage cabinets need to be automated and remotely monitored. This article presents the results of the research and fabrication of low-voltage distribution cabinets; by which, the operator can remotely control the switching, monitor the grid parameters, and manage the power to ensure the power system’s safe, economical, and reliable operation and to provide customers with high reliability and high quality of power supply.
