Scope

Scope: This document specifies the general requirements, functional requirements, and performance requirements for low-voltage distribution network feeder monitoring devices. This document is applicable to the design, procurement, construction (or modification), operation and maintenance, acceptance, and testing of low-voltage distribution network feeder monitoring devices. Main technical content: Given the current issues in low-voltage distribution substations, such as incorrect transformer-to-household transformer relationships leading to difficulties in accurate fault localization and early warning, affecting the accuracy of line loss in the substation; when the three-phase load in the substation is unbalanced, it is impossible to balance it, resulting in accelerated degradation of equipment lifespan; when maintenance is required, there is no effective information update or filing, leading to identification omissions or errors in the later stage, causing the work efficiency of the substation to gradually decline. The operational management level of the low-voltage distribution network directly affects the quality of power supply for users. Low-voltage distribution network feeder monitoring devices can realize the intelligentization and Internet of Things of low-voltage distribution substations, support lean management needs, and solve the above problems. This standard is based on technological leadership, innovation, and scalability, and standardizes the structure, functions, and performance of low-voltage distribution network feeder monitoring devices, thereby guiding industry manufacturers in product design and R&D.
