Manufacturer: Device Setting Caused Super Bowl Outage
The manufacturer of a protective device blamed in the power outage that interrupted the Super Bowl said a low "trip setting" on the equipment caused the partial blackout in the Superdome.
Friday's statement from S&C Electric Co. of Chicago said the outage would have been avoided if the operator of the relay device had set the trip threshold higher.
The statement did not name the operator, but the equipment was owned and installed by Entergy New Orleans, the local electric utility company that supplies power to the dome.
Earlier Friday, Entergy said the device was the cause of the power outage.
The power failure at Sunday's big game cut lights to about half of the stadium for 34 minutes, halting play between the Baltimore Ravens and San Francisco 49ers.
The FBI had ruled out cyberterrorism as a cause.
Entergy and SMG had both upgraded lines and equipment in the months leading up to the Super Bowl. Entergy New Orleans CEO Charles Rice said the new switching gear, with the faulty relay, was installed as part of a $4.2 million upgrade by Entergy, including the installation of a new power line dedicated solely to the stadium.
In a separate project, SMG replaced lines coming into the stadium after managers expressed concerns the Superdome might be vulnerable to a power failure like the one that struck Candlestick Park during a 49ers Monday Night Football game in 2011. That outage was blamed at least partly on a transformer explosion.
But NFL Commissioner Roger Goodell downplayed that possibility after the outage, saying the NFL planned to keep New Orleans in its Super Bowl plans. Mayor Mitch Landrieu said the city intends to bid for the Super Bowl in 2018.
