In the power industry, RTU, DTU , FTU, TTU and other devices are switch monitoring devices in the distribution network automation system, which are suitable for the automation engineering of urban, rural and enterprise distribution. In the power industry, RTU, DTU , FTU, TTU and other devices are switch monitoring devices in the distribution network automation system, which are suitable for the automation engineering of urban, rural and enterprise distribution. 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. The functional advantages of dtu. Each plug-in can select 1 group of three-phase AC voltage and 2 groups of three-phase AC current analog (or other) inputs. The basic contents include voltage, current, frequency, power and power factor, and up to 6 groups of modules can be configured. It can be configured with 6 direct current. 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. 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. Feeder. FTU is the end monitoring terminal of distribution automation. Front end: FTU is the. Data Transfer Unit (DTU), also known as a "data transmission unit, concentrator, converter, or repeater," typically functions as a router or gateway. It supports multiple industrial protocols (e.
