    RTU Wireless Communication Remote Fault Indicator , Underground Fault Distance Locator Data Transmission Easily

    RTU wireless communication fault indicator of cable type data transmission easily


    Data Transmission Unit function is to receive wireless signal from panel indicator then to demodulate and decode,then send the signal to central station by GSM or GPRS.

    Working principle:

    Date Transmission Unit is to transmit the fault signal from panel indicator which is transmitted from short-circuit fault indicator and earth fault indicator through optical fiber. DTU receive data wireless from panel indicator ,then send the fault signals to master station by GSM or GPRS after analysis and processing to realize fault detection and fault location of power distribution network .

    Main characteristics:

    1.Wireless receive:receive fault point information from panel indicator through wireless

    2.GSM OR GPRS send: send status and fault information to master station,requires confirm detailed requirement before order.

    3.Main supply: powered by two roads of powered CT, back up used each other, if primary line current is not less than 10A, back-up power will not be consumed; or PT powered.

    4.Back-up power supply:equipped with free-maintenance 5AH lithium battery. Under condition of no power for main power source, it can keep device working 5-8 years and fault information not lost and no need to complement energy.

    Function

    1.wireless receive: receive fault point signal from panel indicator by wireless

    2.GSM or GPRS transmission: send status information, fault information to master station by GSM or GPRS.

    3. Power supply way:PT supply or two road of CT supply, if primary current is above 10A,it can work normally.

    4. communication protocol:IEC870-5-101 or IEC870-5-104

    5. Remotely upgrade:device can easily be upgraded remotely.
