Overhead Fault Indicator Positioning System

Overhead Fault Indicator Positioning System

Function highlights

The big data platform runs safely and stably. The user interface of the platform is simple and easy to operate, and it is fully functional to meet all the needs of users.

It is used for the real-time monitoring of line status. It can rapidly locate and show the fault location and provide a better user experience through the mobile APP, cell phone SMS alerts pushing and other ways.

Remote configuration of equipment parameters and remote upgrade of collection units and aggregation units can be done without being on-site, facilitating the maintenance and management of equipment.

It is easy to install. The compact, lightweight structure simplifies the installation. It can be installed on live wires by using an adapter and insulating rod.

It has extra long service life. The indicator can draw power from the overhead line and is equipped with a backup lithium battery. The fault indicator uses Four-Faith's proprietary technology. Its battery has 10 years of service life.

Overview

Overview:
The Online Status Monitoring System of Four-Faith's fault indicators is applicable to 5~38KV (can be customized from 44KV, 69KV and 110KV) overhead line distribution network. The fault signal is indicated by three super bright flashing LEDs with 360º visibility, permanent fault, instantaneous fault and battery low voltage alarm can be distinguished and indicated by the three different super bright flashing LEDs. Grounding faults can be indicated by two different alternate super bright flashing LEDs; It is used for real-time monitoring of power lines and operating status and fault detection and positioning. It is a distribution line fault monitoring system with remote transmission capability that features distributed monitoring, concentrated management and instant notification. In the case of non-fault, it monitors the changes in grid load to prevent line faults; in the event of a short circuit and grounding fault in the power line, it displays the fault location in a timely manner, which helps to guide the operations and maintenance personnel to quickly remove the fault and restore power supply, thus ensuring the stable operation of power lines and providing a basis for intelligent decision-making.

Solution introduction

Introduction:
A.Overhead Fault Indicator, Four-Faith's Distribution Line Status Monitoring System, is applicable to overhead lines of distribution network. It is used for real-time monitoring of power lines and operating status and fault point detection and positioning. It is a distribution line fault monitoring system with remote transmission capability that features distributed monitoring, concentrated management and instant notification. In the case of non-fault, it monitors the changes in grid load to prevent line faults; in the event of a short circuit and grounding fault in the power line, it displays the fault location in a timely manner, which helps to guide the operations and maintenance personnel to quickly remove the fault and restore power supply, thus ensuring the stable operation of power lines and providing a basis for intelligent decision-making.

B.Wave-Recording Fault Indicator, Four-Faith's fault (recording) solution, is applicable to 6~35KV overhead lines of distribution network. It is used for real-time monitoring of power lines and operating status and fault point detection and positioning. It is a distribution line fault locating system with remote transmission capability that features distributed monitoring, concentrated management and instant notification. In the case of non-fault, it monitors the changes in grid load to prevent line faults; in the event of a short circuit and grounding fault in the power line, it displays the fault location in a timely manner, which helps to guide the operations and maintenance personnel to quickly remove the fault and restore power supply, thus ensuring the stable operation of power lines and providing a basis for intelligent decision-making.

C.Wall-mounted Cable Fault Indicator, Four-Faith's distribution line status monitoring system (overseas wall-mounted), is applicable to 5 ~ 38kv distribution network cable lines. It can monitor the operating status of cable lines online. When the sensor (current transformer) detects a short circuit or ground fault, the fault current information will be transmitted to the display panel through the copper conductor cable, and the corresponding LEDs on the display panel will flash. At the same time, the display panel will send the fault signal to RTU (information transmission unit) through relay or MODBUS, and then RTU will send the received fault information to SCADA system platform, and SCADA system platform will display the fault information and fault location synchronously to help users identify and locate the fault point quickly.

Feature and Benefit

1. Wave-Recording Fault Indicator uses high-speed digital sampling technology.

2. Combines the advantages of 4G/3G and LoRa in terms of communication to ensure the terminal is always online.

3. It uses high-precision three-phase synchronized timing based on GPS clock signals with Four-Faith's unique algorithm to achieve high synchronization performance. The three-phase wireless synchronous time service has an accuracy of less than 100μs.

4. Overhead fault indicator positioning system supports multiple reset methods, including automatic reset, timed reset and remote reset.

5. Low current (5A) self-charging design ensures real-time and stable online operation.

6. Overhead fault indicator positioning system can be triggered in a smart way to capture small current ground fault transient current and ground electric field transient waveform signal.
