In June 2009 Duke Energy activated a network of intelligent switches and line sensors in Hendersonville, N.C. creating our company’s first “self healing” network. It’s called “self-healing” because the equipment reroutes power automatically when there is trouble to reduce the number of customers affected by power outages. 

The system was put to the test on June 23 when a tree on Lower Ridge Blvd. fell across some power lines. When the lines came down, the network kicked in immediately to diagnose and reroute power. The self-healing network saved over 1,500 customers from experiencing a sustained power outage. Customers served by this self-healing network may have experienced a few blinks or a brief outage as the devices activated to reroute power. Only the immediate customers served by the affected lines remained without power.  

See for yourself how it works.
