Intelligent Fault Indicator VS Traditional Monitoring Mode

Do you remember when the last blackout happened? With the development of smart grid system, more and more node monitoring systems such as fault indicator are applied to transmission and distribution network, which greatly improves the work efficiency of line operation and maintenance personnel, as well as long-time sudden power outage is more and more rare.

However, due to the high cumulative purchase cost of existing fault indicators and a large number of regular maintenance work, power companies are often unable to deploy more fault indicators in the huge power infrastructure, so there are still many places, especially the relatively poor areas, that can only use the backward way of manual line inspection. It is necessary to design an intelligent fault indicator with easy implementation, less maintenance and low cost.

 

 

Key points of fault indicator: accurate perception and rapid positioning

 

The line fault indicator is used in transmission and distribution lines, power cables and switch cabinet incoming and outgoing lines to indicate the flow of fault current.

 

Under the traditional operation mode, when the line has short circuit, grounding, overload and other faults, the line operation and maintenance personnel need to patrol the whole line to find the fault point, which consumes a lot of time.

 

In the new transmission and distribution network, the fault current indicator can quickly and accurately find out the fault section according to the line current mutation and capacitance current change, and upload the relevant data to the monitoring and analysis center through the communication terminal. According to the fault signal, the maintenance personnel can quickly locate the fault section, isolate the fault point, timely restore the power supply in the fault free area, shorten a large number of fault inspection time, and save manpower and material resources, reduce the outage time scope, then improve the reliability of power supply.

 

In the application of the underground fault indicator, the fault indicator is located at the cable termination of each main cable. The indicator upstream of the fault will trip while the indicator downstream of the fault will remain in the non trip position. In this way, the operation and maintenance personnel can easily find the fault part of the cable or equipment without going through the time-consuming fault isolation process.

In the application of the overhead fault indicator, the conspicuous display screen on the fault indicator can guide the line operation and maintenance personnel to the part of the problem.

 

 

The Big Data Analysis Helps Improve Efficiency and Reduce Cost

 

With the maturity of 5g technology with large bandwidth, low delay and high reliability, power companies are also promoting its application in line inspection, distribution network status monitoring, big data acquisition, quasi load control, distribution automation, and etc. By collecting data at nodes with higher accuracy, better networking capability, and lower maintenance costs, power companies can identify and respond to blackouts more quickly and reliably.
