When faults or a single loss of source occur on an underground residential lateral circuit, the EdgeRestore system automatically locates the fault, isolates it, and reroutes power from an alternate source.

This happens automatically, restoring power to the circuit without a crew—all in less than 60 seconds. Eliminating the outage maintains power for dozens of customers and also prevents an emergency truck roll, trimming your O&M costs.

Locating and isolating underground faults can be a painstaking operation for your crews as they go to multiple transformers to physically find the issue. Additionally, manually moving cables can expose crews to medium voltage if the line remains energized, and there is a risk of closing back into the fault with an elbow rated only for one-time fault-making.

The EdgeRestore system prevents lengthy trial-and-error fault-hunting. Additionally, crews can use vacuum interrupters instead of separable connectors to the switch, reducing crew exposure to medium voltage and the risk of closing into a fault.

The EdgeRestore^® Bushing Well Interrupter fits into existing protection schemes without the need to reconfigure curves—removing upfront work for your teams. Setup is simple, with no need to install computers, batteries, software, radios, or antennas.

When the devices operate, each EdgeRestore Bushing Well Interrupter uses peer-to-peer communication via the power line carrier to isolate the fault and restore service. The step-by-step process is automatic, and power is restored in less than a minute.
