Quang Nam Power Company is managing and operating 80 reclosers- the devices that have the function of auto opening and closing in case of transient faults on the medium voltage lines.
To be able to proactively open and close and monitor the status of the circuit breakers in case of changes, the operators need to come to the location of the circuit breaker for manipulating. For the circuit breakers that are located in the complex terrain and difficult to get access, the mobilization of operators to check and reclose the circuit breakers will take time and prolong the outage duration of customers and therefore affect the reliability of the power supply.
Remote control and monitoring of the circuit breaker on the line.
Before the increasing requirements on the power supply reliability index, Quang Nam Power Company has deployed installation of the remote control and monitoring devices for circuit breakers- reclosers.
Mr. Phan Van Hai - Deputy Head of the Load Dispatch Division of the company said: Through the remote control and monitoring systems- reclosers, the dispatchers can monitor the status of the equipment, check the current and voltage values of power supply for the region, analyze the causes so as to take measures in a timely manner; at the same time can open and close of the circuit breakers in case of faults on the lines.
"The real test results showed that the device is working properly and reliably. The operation is fast and the information provided is accurate. The deployment of reclosers, the remote control and monitoring system for circuit breakers will contribute to reduce the outage duration of the customers and enhance the reliability of power supply.”, added Mr. Hai.
With the goal of improving the quality of customer services, Quang Nam Power Company has continuously invested in and upgraded the power system in the entire province. The installation of the reclosers contributes to improving the power supply and minimizing outage duration for customers.
