Overhead Line Fault Automatic Location System

The FCI-100 series overhead line fault automatic positioning system is an automatic and efficient fault detection and positioning system composed of overhead fault indicators, data forwarding stations, variable load cabinets, and backend monitoring systems. It is mainly used for the detection and rapid positioning of short circuits and grounding faults in distribution systems. This system features remote transmission capabilities and is a distributed monitoring, centralized management, and instant notification model for power distribution automation construction. The backend fault positioning software works in conjunction with the on-site fault detection and indication devices, allowing the fault location and occurrence time to be displayed on the backend interface within a few minutes after a fault occurs, while also sending

1. Overhead Line One Remote Fault Automatic Location System

System Overview

The overhead line "One Remote" fault automatic location system consists of overhead type "One Remote" fault indicators, "One Remote" data forwarding stations, variable load cabinets, and a backend monitoring system, forming an automatic and efficient fault detection and location system. It is mainly used for detecting and quickly locating short circuits and grounding faults in the distribution system.

This system is a distributed monitoring, centralized management, and instant notification type of distribution network automation construction model with remote transmission capabilities. The backend fault location software works in conjunction with the on-site fault detection and indication devices, allowing the fault location and occurrence time to be displayed on the backend interface within a few minutes after a fault occurs, while forwarding the fault location results to the designated personnel's mobile phone number, helping maintenance personnel quickly reach the site, eliminate faults, restore normal power supply, improve power supply reliability, and significantly reduce the number of fault patrol personnel, thus enhancing work efficiency.

System Functions

Achieve rapid fault search and location, reducing fault inspection and handling time.

System Features

• Fast fault location: accurately locate the fault section within 2 to 5 minutes;
• Accurate fault location: short circuit fault accuracy can reach 99%, grounding fault accuracy can reach 90%;
• High investment cost performance: saves more than 50% compared to traditional automation construction solutions, with a wider coverage for the same investment amount;
• Convenient engineering construction: no need to modify existing equipment, installation and disassembly use special tools, no need for power outage operations;
• Flexible operation mode: can operate independently as a rapid repair platform for distribution network faults, or as a "One Remote" module in the distribution network automation system, with good scalability and compatibility;
• Simple communication method: indicators use wireless communication; data forwarding stations use GPRS/SMS communication.

Applicable Scope

• Small and medium-sized cities, county-level distribution network automation construction model;
• Urban distribution network automation overhead radiation lines or line branch renovations;
• Application areas: C/D/E class power supply areas.

2. Overhead Line Two Remote Fault Automatic Location System

System Overview

The overhead line "Two Remote" fault automatic location system consists of overhead type "Two Remote" fault indicators, "Two Remote" data forwarding stations, variable load cabinets, and a backend monitoring system, forming a fault detection, location, and load monitoring distribution network management system. It is mainly used for detecting, quickly locating, and monitoring loads for short circuits and grounding faults in the distribution system.

This system is a distributed monitoring, centralized management, and instant notification type of distribution network automation construction model with remote transmission capabilities. The backend fault location software works in conjunction with the on-site fault detection and indication devices, displaying the current load changes in real-time on the backend interface during normal line operation, and accurately showing the fault location and occurrence time within a few minutes after a fault occurs, while forwarding the fault location results to the designated personnel's mobile phone number, helping maintenance personnel quickly reach the site, eliminate faults, restore normal power supply, improve power supply reliability, and significantly reduce the number of fault patrol personnel, thus enhancing work efficiency.

System Functions

Achieve rapid fault search and location, reducing fault inspection and handling time;

Achieve monitoring of line load current, meeting the basic needs of distribution network operation management.

System Features

• Fast fault location: accurately locate the fault section within 1 to 3 minutes;
• Accurate fault location: short circuit fault accuracy can reach 99%, grounding fault accuracy can reach 90%;
• Precise load monitoring: load current collection accuracy of 2%, automatically forming load curves for query;
• High investment cost performance: saves more than 50% compared to traditional automation construction solutions, with a wider coverage for the same investment amount;
• Convenient engineering construction: no need to modify existing equipment, installation and disassembly use special tools, no need for power outage operations;
• Flexible operation mode: can operate independently as a rapid repair platform for distribution network faults, or as a "Two Remote" module in the distribution network automation system, with good scalability and compatibility;
• Simple communication method: indicators use wireless communication; data forwarding stations use GPRS/CDMA communication.

Applicable Scope

• Small and medium-sized cities, county-level distribution network automation construction model;
• Urban distribution network automation overhead radiation lines or line branch renovations;
• Application areas: A/B/C/D class power supply areas.
