This kind of device is applied to the overhead power distribution network automatic system from 6KV to 35KV,is used to improve the safe and reliable operating performance through centralized monitoring the current, temperature and fault condition on the power distribution circuit.

System Composition Structure and detailed instruction:

This system of device is composed of communicable fault passage indicator, data transmission unit, main station software and hardware.

1)Wireless receiving and sending: receive the fault information from fault points sent by wireless transmitting probe

2)Sending SMS: send fault information to central station through the communication of GSM, GPRS, RS232,RS485 and Ethernet.

3)Reserve power supply: equipped with solar panel, used for charging to storage battery. In case of no main power supply, reserve power supply can be seamlessly connected and keep the DTU work smoothly.

DTU structure characteristics:

1) Weight including solar panel: 7kg

2)Install mode: installed on overhead line poles

3)Anti-rust and corrosion resistance: the parts are made of anti-rust and corrosion resistance materials

Serials number instruction:

1)Each FCI has one code, describes communication code and phase position (A, B,C) of FCI. For example, “A”in the code means this indicator must be installed line A, “1234567” is the code of FCI itself, when installed, users must make detailed records.

2)Each DTU has its own code which is on behalf of DTU address itself. when installed, users must make detailed record for this code.

Inspect before installation:

You must check if the communicable FCI is in a normal state( no red flag and sometimes flashlight , belong to normal phenomenon). If some FCIs don’t reset (always display red flag), you please notice the FCI code to manufactures, and also, please make detailed records for installation site when FCI is installed so that you can replace it more easily.

Switch on the communicable FCI before install and make sure the power indicator is flashing, which is in a normal state. If there is abnormal phenomenon, please notice your supplier, and also, make detailed records for the installation site so that the FCI can be changed more easily.

install and uninstall:

Notice: strictly prohibit persons from sitting under the indicators during the installation process so as not to be injured.

Special Notice: please make good records for the install site and indicator codes.

There is type test report for it, test items as following:
