Safety criterion
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. When received, the repeater station shall be carefully checked for damage during transport, and in case of any problem, the carrier shall be reported immediately in written.
The package shall be carefully handled to avoid the damage and impact, the water shall be prevented during transport, and the corrosive materials cannot be transported in the same truck box as the package absolutely. If the equipment needs to be stored for a very long time before installation, it shall be in the clean place with good ventilation, the corrosive gas shall not be contained in the air, and it shall be stored with caution to avoid damage.
Device description
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.
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. In addition, the indicator also has current measurement and wireless data communication capabilities, by sending the fault signal to FTU,in order to comply the function of the remote communication and the remote monitoring, to help operators to find the point of failure quickly and shorten the outage time and improve reliability.

Principle of Fault Indicator
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. After the indicator is installed, the line current has been measured . The lineman simple follows the flashing fault indicators all the way to the first non-flashing fault indicator, thereby identify the fault location.The terminal device receives the fault information can further upload,
