Wireless Data Communication Voltage Indicator Device , Mobile Phone Ground Fault Tester 

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.

In order to avoid the unexpected conditions during application, the following safety guidelines shall be observed:

1. The Operating Manual must be read carefully during the site installation and debugging;

2. The power supply must be off when the mobile phone card is inserted or extracted via GPRS module;

3. The address information of data repeater station and the setup information of GPRS module must be recorded in detail;

4. The lead from solar energy to power panel must be reliable;

5. The installation of data repeater station must be reliable, and the solar panel shall face south (the direction with longer sunshine duration);

6. The person is strictly prohibited to stand under the pole and tower during installation.

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. The indicator also has current measurement and wireless data communication capabilities.

Main features

    GSM and GPRS 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.The equipment program can be upgraded conveniently through master remote maintenance station.The terminal can be in the two-remote or one-remote working mode by setting the intrinsic parameters of remote terminal uint.Through built-in low-power RF modules achieves short distance wireless communication.The lineman simple follows the flashing fault indicators all the way to the first non-flashing fault indicator, thereby identify the fault location.
