DTU is a terminal device of a switching station, generally installed in conventional switching station, outdoor small switching station, ring network cabinet, small substation, box-type substation, etc. It completes the acquisition and calculation of position signal, voltage, current, active power, reactive power, power factor, electric energy and other data of a switching station, performs the switching and closing operation of switches, realizes feeder switch's fault identification, isolation, and recovery power supply of non-faulty areas. Some DTUs also have the functions of protection and automatic switching of backup power supply.
