When there’s a problem — or a fault — on a power line, it can cause power outages for our customers. But thanks to a game-changing new system, these problems impact fewer customers than ever. The new system, created by our own engineering teams and vendor partners, uses smart devices that interrupt faults remotely. They’re called “vacuum reclosers.”
We place them on power lines to monitor the flow of electricity. When a sensor on a line detects a problem, the nearest recloser automatically cuts power from that point in the line. Instead of every customer on the line losing power, only customers downstream of the recloser device are impacted. Then, our crews work as safely and quickly as possible to restore power to everyone who is out.
In November 2021, we installed the first vacuum recloser on a transmission line and plan to install more of these devices at locations that will provide the most benefit to our customers.
This is just one example of our commitment to innovate and invest in technologies that improve reliability.
