The Benefits of Using Supercapacitors for Recloser Back-Up Power

Posted by Peter Matthews on Feb 5, 2025 8:00:00 AM

To protect electrical grids from overloads and faults, utility companies can incorporate reclosers. When a fault occurs, this high-voltage circuit breaker automatically closes to isolate the faulty sections of the grid, allowing other areas of the grid to continue to operate safely. The recloser can then automatically test the electrical lines to determine if the issue has been resolved and reset itself, restoring power more quickly once a fault is cleared. Reclosers are also designed to perform remote switching, enabling utilities to manage their networks more efficiently.
