Abstract
On April 1, 2005, a faulted lightning arrester resulted in the loss of off-site Circuit 751. With the electrical system in a 50/50 alignment, the loss of Circuit 751 resulted in the loss of safeguards busses 16 and 17. The B Emergency Diesel Generator (EDG) started automatically and re-energized the safeguards busses as designed.
Corrective action to prevent recurrence is outlined in Section V.B.
