I may not be an electrical engineer, but...
The game was so-so, so I didn't stroke out in front of my new ghetto-screen teevee, but the most interesting part was the power dump, which some self-annointed engineer, hired for the purpose by Fox News, completely failed to explain this ayem, so here's my best:
Take the following facts in the following order:
- It's New Orleans, which rebuilt the Super Dome after Hurricane Katrina, expecially the dome. One might reasonably expect that they refurbished or replaced the HVAC system at that point, so it's relatively new, and wired to the lates codes, or is it?
- It's New Orleans, known for it's graft under previous Administrations.
- The standard scam for building contracts (from the scammer point of view) is that I, the Administrator of the contract, award you, the subcontractor, a juicy sub-contract in return for paying me (kicking-back) 10% of the contracted amount for that subcontract. Because of that nearly-universal practice, the subcontracts are almost always shorted by the 10% as to their completion. In an HVAC contract, that shorting could easily be made up in the complexity and sufficiency of the wiring.
- At half-time, there were a lot of pyrotechnics shot off, all generating a large amount of smoke, which had to be rapidly pushed out of the cavernous building in time to play the game within a few minutes. That takes huge ventilating capacity to accomplish.
- The combination of bringing all the inside lighting back up to full-bright, and running the exhaust fans at full power to clear all the fireworks smoke, created a maximum load for the building's electrical system.
- The cheapened wiring meant that there was a weak leg in the wiring system, and the emergency sensors detected a pending overload, and tripped the breakers, darkening half the stadium.
That's probably how it happened, folks. If it did happen this way, it will happen again. Maybe next time, it will be actually investigated.
Or, maybe you could just go to Ray Nagin and ask him what he did with the 10% of that sub-contract, get it back if he still has it, and fix the wiring of the SuperDome.
