During Sunday's game, the relay device triggered, signaling a switch to open when it shouldn't have, causing the partial outage.

In some cases, it can use one mobile device to relay power to another, keeping everything fed even if the main power hub is tied up.

That led the relay, a kind of sensing device, to incorrectly conclude there was an electrical problem and tell a nearby electrical switch to isolate the perceived problem, reducing the flow of power to the Superdome during the game's third quarter.
