7 - 69KV Cable Fault Indicator , Wireless Power Supply Failure Indicator 

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.

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.

 Work mode

    The terminal can be in the two-remote or one-remote working mode by setting the intrinsic parameters of remote terminal uint. It can be upgraded conveniently through master remote maintenance station.GSM (short messages) and GPRS (data) are mutually the standby mode.

The details

1. Wireless receiving: the fault point information and load current information sent by indicator are received via short-range wireless network mode.

2. GSM or GPRS forwarding: 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.

3. Solar power supply: the solar power supply mode is applied, and the maintenance-free 8AH lead-acid battery or 12AH lithium iron phosphate battery is provided, with the working temperature range of both batteries of -35℃~75 ℃ and -20℃～75℃ separately.

4. Optional communication protocol: IEC870－5－101 protocol or 104 can be selected for the connection with the third party equipment to upload the fault and shift information.

5. Remote upgrade: the equipment program can be upgraded conveniently through master remote maintenance station.

6. Convenient maintenance: the parameter setting and equipment maintenance can be performed conveniently via wireless setting terminal.

7. Event recording: the device can record the maximum 500 pieces of SOE events, providing the rich data support for system fault analysis.
