Power out at Super Bowl

Power out at Super Bowl

Power out at Super Bowl

(OP)
The Entergy folks will have a lot to explain to the football fans tomorrow.

RE: Power out at Super Bowl

It's not the power outage it's the fact that the stadium obviously has loser antique metal halide ballasts that can't ignite hot bulbs instead modern electronic ones that will instantly re-strike.

What's the super bowl?

RE: Power out at Super Bowl

I heard a rumor that it had something to with one of the incoming feeders to the stadium.

This morning on CBS they were showing a video taken in the announcement room when the lights went out. One of the guys on a head set mic could be heard saying "We lost a feeder" "need to do a bus tie" and "20 minutes" could be made out in the audio.

They probably don't have feeder automation software either. And as for those Metal Halides it depends on how long the power was out to them. If it was really 20 minutes even instant-re strike models would need time to warm up.

RE: Power out at Super Bowl

There was a report that something simular happened twice during rehursals.

Sounds like they need enhanced service for these basketball games (no don't respond to correct me).

One would wonder why they don't have network service for something where a 30 second ad costs $4 Million.

No I did not watch, but I heard that dog on Jay Leno predicted correctly.

Hey itsmoked,

For a 38-year old stadium, what do you expect? They probably could have had high pressure sodium but HPS would have restart problems too.

With all the eyes on the situation and a future Super Bowl contract, they may have to look at replacing them with LEDs!

RE: Power out at Super Bowl

Some electronic ballasts will restrike in 2 to 4 minutes, but still take some warm-up time.

RE: Power out at Super Bowl

After Katrina, you can book it that all the money the Fed gave them to spruce the place up after it had been used as a hotel by the locals was diverted to other things.

RE: Power out at Super Bowl

In a space like that the only appropriate means of powering the lights is through a UPS type system that can at least maintain output long enough to 1) transfer to an alternate utility source, and 2) when that fails allow enough time for the standby generation to start. It appears that there was emergency lighting, but compared to the venue revenue for a single event like the superbowl, how much could it possible cost to do it right?

RE: Power out at Super Bowl

Sounds like an economic problem, but with almost 0% interest the bond interest would not a huge factor, unless they have maxed out there credit.

I believe S&C has a large size ups system, but not knowing the loading it may take more than one.

RE: Power out at Super Bowl

sibeen,

It's a football game that broke out the other night at the Beyonce concert in New Orleans.

Best to you,

RE: Power out at Super Bowl

Let's give the professor the benefit of the doubt and assume he was misquoted and not talking about the relay.

RE: Power out at Super Bowl

Sounds like S&C Vista pad-mounted SF6 switchgear - unless something older. The standard relay is a proprietary S&C black box (actually made by SEL). It's pretty rudimentary as relays go. No oscillography - I don't think any event reports.
