What is FLISR?
 

FLISR stands for Fault Location, Isolation, and Service Restoration. It is a technology used in power distribution systems to quickly detect, locate, and isolate faults or power outages, and then restore service to the affected areas.

It works by using sensors and communication systems to detect faults in the distribution system. Once a fault is detected, the system automatically isolates the affected section of the network, rerouting power to restore service to as many customers as possible.

The technology can help identify the exact location of the fault, which can make it easier for utility crews to quickly repair the problem and restore power to the remaining affected customers. 

FLISR helps to improve the reliability and efficiency of power distribution systems, reducing downtime for customers, and minimizing the costs associated with power outages.

 

Why Utilities Need FLISR
 

  • Faster fault detection and restoration: FLISR can quickly locate and isolate faults in the distribution system, which helps to reduce downtime for customers. By automating the fault location and restoration process, FLISR can significantly reduce the time it takes to restore power to affected areas.
  • Improved customer satisfaction: Customers expect reliable and uninterrupted power supply, and FLISR helps utilities deliver on that expectation. By reducing the duration of outages, customers are less inconvenienced and therefore more satisfied with the utility's service.
  • Reduced operational costs: FLISR can reduce the need for manual labor, such as field crews dispatched to locate and isolate faults, which can result in lower operational costs for utilities.
  • Enhanced safety: By automating the fault detection and restoration process, FLISR can reduce the risk of injury or accidents that could occur when utility personnel are sent to locate and repair faults.

FLISR applications can reduce the number of customers impacted by a fault by automatically isolating the trouble area and restoring service to remaining customers by transferring them to adjacent circuits. 

 

         

Conclusion

 

FLISR can improve the reliability and efficiency of a utility's power distribution system, leading to increased customer satisfaction, reduced costs, and enhanced safety.
