What Caused Power Outage at Super Bowl: Is 'Abnormality' the Whole Story? (+Video)

Article excerpt

Super Bowl XLVII leaves its share of mysteries in its wake, and one of the biggest is unrelated to football tactics or the inner workings of the Harbaugh family: What caused the power outage just as the second half was getting started?

A power outage left the game in limbo for more than half an hour, baffling commentators and setting the stage for the dramatic near- comeback of the San Francisco 49ers.

Was it a ploy by Chinese hackers to exhibit their capabilities at a moment that had the attention of some 50 million Americans?

Did Beyoncs flashy halftime show overtax the Superdomes circuitry?

The company Entergy, which supplies power to the Mercedes-Benz Superdome, says a sensor discovered an abnormality in the electrical load, triggering the shutdown.

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.

The halftime show and the CBS broadcast were operating on their own power sources, separate from the rest of the stadium, a representative of SMG said Monday morning, according to the news site NOLA. …
