“Shortly after the beginning of the second half of the Super Bowl in the Mercedes Benz Superdome, a piece of equipment that is designed to monitor electrical load sensed an abnormality in the system,” says a joint statement from Entergy and SMG, the management company for the Superdome.
“Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue,” the statement continues. “Backup generators kicked in immediately as designed. Entergy and SMG subsequently coordinated start up procedures, ensuring that full power was safely restored to the Superdome.”
The obvious follow-on question is, What caused that abnormality?
The statement said Entergy and SMG are continuing to investigate for an answer on that “root cause.”
The fault-sensing equipment, the companies added, operated right where Superdome equipment intersects with Entergy's feed of incoming power. An FBI special agent, quoted by The Associated Press, said terrorism didn't cause the power problem.
