30 6:51:09 PM 11,258 customers lose power 30

31 6:51:37 PM Service restored to 10,000 customers Before the 46kv breaker completed the reclose cycle, the distribution automation sensed the loss of voltage, automatically opened and closed switches to reroute power from adjacent 12kv lines. 31

32 6:51:52 PM Service restored to another 800 customers As the 46kv breaker completes the reclose cycle and locks out, the 46kv automation identifies the fault location, then opens and closes switches to energize two of the three stations. 32

33 6:55:04 PM Service restored to 289 customers A dispatcher opens the PIN 201 breaker and closes the first PCR on the PIN 201 circuit. The 289 customers between these two points now have electric power service. 33

34 6:57:47 PM All service restored A dispatcher now opens the PIN 202 breaker and closes the first PCR on the PIN 202 circuit. The remaining customers between these two points now have electric power service. All electric services restored 34

35 Summary January 14, 2013 Storm 11,258 customers lost power due to a tree falling from outside of a right-of-way All customers restored through automation or remote operation within 6 minutes and 38 seconds Minimum number of switching operations required to restore service: 44 Mileage between switches: 315 Restored to normal through automation Without automation several hours of manual switching would have been required to restore service
