The cause of the 34-minute power outage in the Superdome during the Super Bowl in New Orleans remains under investigation and independent experts are being brought in to identify what caused the loss of electricity, officials said.

The power outage at the 38-year-old stadium interrupted play for 34 minutes in the 3rd quarter of Sunday's game, which was won by the Baltimore Ravens.

Outside experts will be hired to conduct the investigation, the Louisiana Stadium and Exposition District, or LSED, Mercedes-Benz Superdome manager SMG and electric utility Entergy New Orleans said.

"Entergy New Orleans, the LSED and SMG will jointly select the independent third party, and prior to selection, the parties expect to discuss the selection with the NFL," the three organizations said in a statement.

Entergy said it was also continuing its own probe of the power outage.

"Shortly after the beginning of the second half of the Super Bowl, a piece of equipment that is designed to monitor electrical load sensed an abnormality in the system. Once the issue was detected, the sensing equipment operated as designed to open a circuit causing power to be partially cut to the Superdome in order to isolate the issue and prevent a larger and more protracted outage," Entergy said.

The power outage marred what had been a week of events showcasing the recovery of New Orleans from Hurricane Katrina in 2005 and celebrating the first Super Bowl in the city since 2002.

The Baltimore Ravens defeated the San Francisco 49ers 34-31 to win Super Bowl XLVII.

The game appeared to be a blowout, with the Ravens leading 21-6 at the half.

Baltimore's Jacoby Jones opened the second half with a Super Bowl record 108-yard kickoff return for a touchdown.

The 49ers bounced back after the power outage, putting up 17 points in the 3rd quarter and 8 more points in the 4th quarter. EFE
