A personal comment on a job that has my shorts more than just a little tight... we're talking about a serious pucker factor here. Next week I am responsible for bringing online six motors at 700 HP each. That's 3.1 Megawatts! :eek:

Okay how does that go? Green to start and red to stop?

Just think about it this way: it's only three-thousandths of a gigawatt!

Whewww. That sounds much better! :rolleyes:
 
And I thought this was about you starting your own business :approve:

He doesn't have deer ticks! You can put your clothes back on now Ivan. :-p

Tsu - thanks for the tip!

btw, I re-stocked your freezer with broccoli. :biggrin:

Oh good! I gave away all of my frozen broccoli to trick-or-treaters and now we have Christmas coming.

I know, I kept thinking of the poor little tykes waking up Christmas morning, running over to their stockings and finding NO FROZEN BROCCOLI in them.

What's Christmas to a child if there's no broccoli in their stocking? :cry: :cry:

(although canned tuna is another must)

That's for birthdays, you silly mentor you. :rolleyes:
 
NO! WAIT! The frozen broccoli is to be given to the Christmas CAROLERS! The tuna's for the cats (and Ivan's birthday gift). :biggrin:

p.s.
Thanx for the broccoli Sis!

Don't forget to dip the broccoli in ketchup to give it the proper complement of holiday colors. :approve:
 
Well, darn!

I hope that's not indicative of how things went.

Well, there used to be this nice little town...

Really things went pretty well. I still can't get over the power going through that place. One leg of the three phase going to each motor consists of something like ten, one inch+ cables! Also, strangely enough, modern drives are so efficient that 480 volt motors were used to replace 3600 volt motors. Historically the I-squared-R losses demand a higher voltage, but the ability to control motor speeds and the ability to idle yield greater gains than the losses incurred due to the increased current.

When we were ready I got a real rise from the crew when I told them how to start the motors; that I didn't want to be anywhere near the place when started. :smile: :smile: :smile: [its always my job to make the final call to start]. I saw about twenty eyes get real, real big.
