Functions

The function and characteristics of the indicator

The GSM fault indicator is composed of 1 communication indicator and 2 satelliteindicators. They send the line status collected by the indicator to SCADA throughthe3G/4G communication module of the communication indicator, and send it to SCADAwhen a fault occurs. , which can quickly notify maintenance personnel and reducefault detection time.

Fault detection and indication

For fault detection, GSM indicator, supports detection of short circuit faults, groundfaults, including transient faults,

a) Permanent Fault

The fault indicator can detect permanent short-circuit fault by electrical field and load current change features. No matter how many automatic reclosing are operated, it is identified as a permanent fault if there is outage.

b) Transient Fault / Temporary Fault

If the fault is cleared by the automatic reclosing cycles and the line returns back to normal state, it is identified as a transient fault.
Permanent Fault

C)Earth-fault Detection

Drop of electrical field is the most important factor for earth-fault detection. The indicator canmeasure a bare voltage value which can reflect the change of electrical field. After earth-fault occurs, there are a large number of transient high-frequency component and bigcapacitive current in the first half wave, and the electrical field will drop at the same time. This feature will be considered as an earth-fault if the transient current up to threshold value.
Earth-fault Detection

Reset Alarm

JYZ-HW-GSM fault indicator has many different reset methods, the main ones areasfollows:

Manual magnet reset, fault reset by test magnet activation/indicator
Automatic reset, when the line is removed and the fault is restored to normal power supply, the indicator resets immediately
Through time reset, the indicator resets at 12h timing,

Function test

After manually activating the indicator with the magnet, the LED light will flash at intervals of 2S, simulating a short-circuit fault. At this moment, the manual magnet can be approached again to the activation part of the indicator to reset; or by automatic reset, the normal load current can be usedto reset

Note: It is not possible to use magnets to simulate faults frequently. It is recommended to test with equipment that simulates lines as much as possible, so that the GSM indicators can be charged in time to ensure their normal operation.

Remote transmission with GSM indicator

For remote transmission of fault information, via 1 GSM communication indicator and 2 satellite indicators. The picture below is the scene simulation picture

Overhead line

The message transmission between the GSM indicator and the satellite is realized by radiofrequency technology, and the maximum communication distance can reach 100 m. GSMindicator transmits fault information and device address to Four-Faith fault location platform/user platform through 4G/3G network
Network Instruction

GSM indicator and satellite indicator communicate RF

The GSM indicator communicates with the satellite indicator and communicates through RFwireless radio frequency technology. The GSM indicator and the satellite indicator have a corresponding communication group frequency address. The communication address of the GSMindicator and the communication address of the satellite indicator need to be maintained. Consistent

The following work needs to be prepared for RF communication:

Prepare a PC, install the corresponding USB driver and place the maintenance software in the PC.
Install the USB driver in the PC,
Prepare a USB debugging tool
Prepare a GSM fault indicator
Use one GSM indicator with two satellite indicators
When the C-phase has no current, use 10 to call the call duration, and use 1 to call when there is a current greater than the threshold 5A.

Connect the tooling to the computer and open the fault indicator maintenance software folder
Click “Fault Indicator Maintenance Software V2.0.3.3.exe” to open the maintenance software, select the indicator type “New 2 Remote Light Overhead Indicator–Three-color Light”, and select “LB-FF” for the communication protocol
After entering the indicator maintenance software, select the corresponding correct serial port number, select “57600” for the baud rate, and then click to open the serial port. 4. Click “RF Parameters – Local Parameters” above, and click “Read Parameters” on the right. Read tooling parameters (synchronization type must select “1”)
GSM indicator, the special frequency band is “0” (mainly used for magnet wake-up), if youneed to use broadcast search, the calling frequency band is the same as the frequency band of the indicator being searched (need to know the indicator frequency band).

Magnet strong search indicator steps:

Use the strong search method to search the indicator, and set the call duration to “0”
Put the magnet in the upper corner of the indicator next to the spring antenna, so that the light turns from off to on, then off to on and then off again (twice on and off), remove the magnet fromthe indicator, and turn on the three indicators in turn. do this.

GSM – Communication

The GSM communication indicator collects the data of the satellite indicator and its own line, andtransmits it to the Four-Faith fault location platform through the 3G/4G cellular network. The GSM indicator communication includes the following data:

Supports short circuit fault detection
Supports ground fault detection
Supports instantaneous short circuit/ground fault detection
Upload interval 48H
Support mutation upload
The uploaded content includes fault data (so it refers to front load current, fault current, fault type, battery voltage, temperature, indicator status, battery strength)
indicator is dormant during non-fault and communication
Support load 10A overhead line indicator can start normally
Support 60HZ overhead line
Support 12h timing reset
Meet 44KV/69KV overhead line voltage
Meet the installation altitude of 4500m environment
Supports magnets to manually activate the indicator
Communication indicator supports communication with platform over 2G/3G/4Gcellular network
Satellite indicator and communication indicator support wireless communication,

Configuration, local

Open the GSM Indicator Configuration Tool, “Remote Configuration Tool”

Remote Instruction

Fill in the parameters of the remote platform and connect to the Four-Faith fault locationplatform，Parameters include:

Indicator code
SCADA IP address
Port
APN
GPRS parameters

Through the configuration of the GSM indicator, the collected permanent faults andtransient faults of the line can be sent to the Four-Faith fault location platform.

Maintenance

During the battery life, the device is maintenance-free. After the battery is discharged, it can be replaced by the user or the manufacturer. Battery life depends on the number of overcurrent faults and reset time. The device can be returned to the manufacturer to ensure proper disposal.

Change of batter

To replace the battery, first open the cover (picture 1) and disassemble the GSMindicator, pull out the pcb components, (picture 2).
Cut the cable ties securing the battery Replace the battery with the correct type (Figure3).
Be careful to reconnect the battery with the correct polarity. (Figure 4

Preparation and Installation

Installation

Before installation in the field

Reconfirm the communication parameters configuration of indicators and DCUbefore the installation in the field, such as group address, frequency, IP address, and port. Andmake sure the SIM card is in service and insert correctly

Mounting

The indicators are mounted onto the overhead line with a special hot-stick installation
tool (picture a). First of all, put the indicator into the drum, and open the split coil CT with thumb andfixit (picture b). Secondly upwarp the spring with tool and fix them (picture c, d). Positionthe conductor between the open split coil CT, and with a forceful upward movement, install the indicator to the overhead line (picture e). When the indicator receives sufficient pressure, the spring will release and clamping the line, and the installation tool will separate from the indicator (picture f).
