fault passage indicator for overhead lines

Smart Electricity Distribution Network Monitoring System

Smart electricity distribution network monitoring system is the use of electronic information and communication technology to detect the distribution network’s short circuits and single-phase ground faults. It enables real-time monitoring, threshold warnings, fault session detection and sending out the fault message. This allows technical personnel to arrive on-site and fix the relevant problems quickly. This system can reduce the reliance on technician experience to identify faults, increase equipment stability and management efficiency. 

Application Scenarios

Widely used in cities with overhead electricity lines, cable lines, oil fields, switchgears and other boxed equipments.

System Composition

The system consists of the fault indicator (acquisition unit), collecting unit and main station server.

Fault indicator (acquisition unit):

Fault indicator is the basis of the whole system; it’s used for collecting real-time data from all test sites.

Collecting unit: When fault indicator detects short circuit or earth fault, the turnover alarm and flashing red light will be triggered immediately, at the same time, the fault information will be transferred to the collecting unit wirelessly through 433M/Lora, and the collecting unit will report it to the main station server through GPRS/CDMA (2G/3G/4G).

Main station server: When the main station server receives the fault information, together with GIS system, the system will provide the time and location information where the fault occurs, to help the maintenance staff identify the fault and fix it in a timely manner.

Abnormal Monitoring Indicators, Automatic Flashing, Turnover Alarm And Sending To Main Station Server

When there is a fault in the electricity line, the LED light will flash immediately and the alarm will sound. At the same time the fault information is transmitted to the main station server. Once the fault information is received, in combination with the GIS system, the fault location and time will be sent out to a technician who will then rush on-site to fix the problem.

Visible Faulty Site and Clear Line Status

When the main station server receives the fault information from the terminal, it will perform a topology analysis, calculating, together with the GIS system to display the fault sites graphically, and clearly displaying the line status.

Powerful Electricity Solutions

1. Powered by electricity line: 10A+ current from the electricity line would be enough for the fault line indicator, extra battery power is not needed in this case.

2. Powered by solar energy: The terminal is powered by solar energy, backed up with a high-capacity lithium battery, can operate normally for 30 days in wet/raining weather conditions.

3. Low power optimization: The indicator uses an ultra-low power consumption design; average power consumption is less than 20 uA.

4. Battery power detection: System will detect power of the backup battery automatically, and will report to the main station server when the power is lower than the preset threshold value, and will have a reminder for you to change the battery.
