This paper discusses the life cycle management of power distribution equipment and the life cycle cost of power dis-tribution equipment digitization. The digitization of power distribution equipment helps improve the automation of distribution systems and the level of operation and maintenance of power distribution equipment. However, whether digitalization has a return on investment requires quantitative analysis. This paper starts with the theory of life cycle management of power distribution equipment and analyzes the key issues of life cycle management of power distri-bution equipment, including the impact on the power supply reliability, operation and maintenance of power distribu-tion equipment, and their life cycle costs. By calculating the life cycle cost of digital distribution equipment, this pa-per quantitatively analyzes the return on investment of digital distribution equipment. In general, the return on in-vestment of power distribution equipment is positive. For important loads, the return on investment of power distri-bution equipment is better.
