Welcome to use remote transmission unit manufactured by us. Each remote terminal uint has already experienced the complete assembly, test and inspection, also the careful check and adjustment before delivery, which has been in good condition when transport.
Remote terminal uint is the data acquisition and communications forwarding device for power distribution network load monitoring, fault detection and positioning system, which can be set as the practical distribution terminal device of two remote (remote signaling, telemetry) functions in the distribution automation system via terminal parameter configuration, which can also be set as the traditional distribution terminal device of remote fault positioning system.
Remote terminal uint is to process and analyze the information from overhead indicator sent via wireless and then send the circuit load current and fault information to the main distribution network station via GSM short messages or GPRS communication.
The fault indicator for overhead distribution lines is used indicating of phase-to-phase and phase-to-earth faults by determining short circuit, over-current and power features to detect faults and provide a local light indication.
Remote terminal uint is to receive the circuit fault information and circuit load operation information from overhead indicator installed in the circuit via wireless for analysis and compiling and then sends the information to main distribution network station via GPRS/GSM communications, to realize the online monitoring, fault detection and positioning functions of distribution network.
The fault indicator installed on the overhead lines, which clipped on each phase so that to detect current and Voltage signal in this phase using itself clipped line structure. Through the low-power chip, it completes current calculation, short circuit, ground fault detection, and through built-in low-power RF modules achieves short distance wireless communication.

Remote terminal uint is Wireless receiving: the fault point information and load current information sent by indicator are received via short-range wireless network mode.GSM (short messages) and GPRS (data) are mutually the standby mode, which are used to send the substation condition, circuit load current, indicator status and fault information to main distribution network station, to ensure the reliable transmitting of distribution network fault information.And it is applied by the solar power supply.The equipment program can be upgraded conveniently through master remote maintenance station.The parameter setting and equipment maintenance can be performed conveniently via wireless setting terminal.At last, the device can record the maximum 500 pieces of SOE events, providing the rich data support for system fault analysis.
