Detailed Product Description
Send The Signal: By GSM Or GPRS GSM Or GPRS Transmission: Send Status Information, Fault Information To Master Station
Remotely Upgrade: Device Can Easily Be Upgraded Remotely Wireless Receive: Receive Fault Point Signal From Panel Indicator By Wireless
High Light:

dc ground fault detector

,

cable break tester

connecting wireless indicator for undergroud cable receive fault point information through wireless effection

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.

Wireless Remote Fault Indicator , GSM / GPRS Power Cable Fault Locator System  0

TYHD-A1 panel type fault indicator(be called indicator for short below) is mainly used for switch gears for locally indicate short circuit fault and earth fault and also provide wireless signal output .

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 .

Characteristics:

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

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

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.

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

Technical parameters:

DTU size height×width×thickness=330mm×230mm×90mm
weight <5Kg
Rate working voltage PT power supply;For CT supply,primary line current is not less than 10A
Static power consumption <1mW
wireless receive distance ≥10m
Wireless frequency 433MHz or 865-869MHZ
