This page is a practical guide for designing feeder automation terminals (FTU, DTU and TTU) with the right mix of sensing, communication, power, security and IC choices. It helps map real grid scenarios into a robust architecture, a realistic checklist and brand-ready. Distribution Automation Terminals (DTU and FTU) by Application (Substation, Pole Mounted Switch, Distribution Transformer, Others), by Types (Distribution Terminal Unit (DTU), Feeder Terminal Unit (FTU)), by North America (United States, Canada, Mexico), by South America (Brazil, Argentina, Rest of. DTU distribution network automation terminal is such an intelligent device, which can greatly improve the efficiency of distribution network management and reduce human errors, and provide timely and accurate monitoring and control of the power distribution system. It helps map real grid scenarios into a robust architecture, a realistic checklist and brand-ready component selections. Feeder. nd challenges for a vast number of medium-to-low voltage distribution automation production enterprises in China. The State Grid Corporation of China (SGCC) proposed an overall principle: “the automated terminal DTUs/FTUs of the distribution network must take into account the requirements of. A DTU distribution automation terminal is used for solving the technical problem that the existing terminal box can not better adapt to the installation requirement of the field undulating terrain, thereby causing more time and labor consumption for installing the terminal box, and comprises a.
