Cause found for Superdome failure

An outside expert investigating the cause of a partial power
outage during Super Bowl XLVII has confirmed that the failure
occurred because a relay device malfunctioned.

Utah-based forensic engineer John Palmer released his findings
Thursday.

Entergy, the company that supplies electricity to the Superdome,
and the stadium’s management company hired Palmer to perform an
independent analysis of the Feb. 3 outage.

Entergy has said it believed the outage was caused by an
electrical relay device it installed specially to prevent a power
failure at the dome. Entery New Orleans President and CEO Charles
Rice says the company is pleased that Palmer’s analysis confirmed
the relay operated in an unpredictable manner.

The partial blackout delayed the game between the Baltimore
Ravens and San Francisco 49ers for 34 minutes.
