A power outage that stopped play during this year's Super Bowl was caused by a faulty device, meant to prevent a power failure.

The energy company that supplies electricity to the Superdome hired an outside company to investigate what happened.
     
It turns out the electrical relay device specifically installed to prevent a power failure malfunctioned.
     
The blackout delayed the game between the Baltimore Ravens and San Francisco 49ers for more than half an hour.
