TripSaver II reclosers provide an advanced lateral protection strategy to manage the 80% of overhead faults that are temporary. TripSaver II reclosers combine the best aspects of fuse-saving and fuse-blowing strategies to improve system reliability. They prevent temporary faults from becoming sustained outages, and they avoid momentary interruptions on feeders by only blinking the affected lateral. By mitigating a significant amount of outages, TripSaver II reclosers dramatically improve SAIDI and SAIFI scores.

Because TripSaver II reclosers prevent temporary faults from becoming permanent outages, the devices help you avoid unnecessary truck rolls and O&M expenses. These savings can quickly add up, especially if crews often travel long distances to reach faults at the grid edge. TripSaver II reclosers are so effective they pay for themselves in four avoided truck rolls, translating to savings straight back to your bottom line. Calculate how much you can save by installing TripSaver II reclosers on your system.

Outages are becoming unacceptable to customers—even if the outages only last a few seconds. Outages can cause costly disruptions to businesses and households alike, especially those at the edge of the grid that typically wait longer for power to be restored. By helping keep these customers’ lights on, TripSaver II reclosers improve customer satisfaction, sparing them from the frustrating and expensive consequences of outages.

TripSaver II reclosers replace fuses on lateral lines. Most fuses expel debris and sparks when they operate for both temporary and permanent faults. However, in place of the fuse, TripSaver II reclosers use vacuum interrupters that do not expel debris and sparks, which helps mitigate the risk of wildfires. The reclosers also have a Non-Reclose mode, a feature recommended so operators can disable reclosing during periods of heightened risk.

Powered by load current, TripSaver II reclosers effectively protect lines without a battery. When a permanent fault does occur, TripSaver II reclosers drop open, requiring crews to visually inspect the line, repair the issue, and manually restore power. Click here to learn more about S&C’s full suite of fire-mitigation solutions.
