The failure of a device meant to protect the power supply to the Superdome caused the Super Bowl blackout, the stadium’s power company said Friday as it took the blame for the outage that brought the game to a halt for more than a half-hour.
Officials of Entergy New Orleans, a subsidiary of New Orleans-based Entergy Corp., said the device, called a relay, had been installed to protect the Superdome from a cable failure between the company’s incoming power line and lines that run into the stadium.
Company officials said the device performed without problem during January’s Sugar Bowl and other earlier events.
They said the device has been removed and replacement equipment will be installed.
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.
