Thanks to Nick for these

I Though you guys might be interested in this.

Pic 1

These are 1250HP 4160V motors we will be hooking up as soon as the building is finished. They are controlled by VFD’s in another building but they are not on site yet. In the background you can see 3 of the 6 (measly in comparison) 200HP 480V motors. On another part of the job there are 2250HP motors. They are not on site yet though.

Pic 2

These are three of the 5 12.47KV – 4160V drive isolation transformers. One for each motor.

I would love to make those terminations!

I've never worked on a motor that used 4160 (but I do MV splicing fairly regularly) - what are they for?

"what are they for?"
The slab you see is actually an 18" thick concrete deck. Underneath is a large concrete tank. The tank receives water from the Microfiltration building that is ahead of it in the system. These pumps pump the water into and 84" pipeline down to the next building in the process, Revers Osmosis.
BTW: You can judge pretty well from the Carpenter in the background but the top of the motors are about ft above the slab. I was told the Millwrights set at least one of the 2250HP motors today. I'll try and get down to that part of the job in the next couple days to get a pic.

It's probably more info than most would want but here is a link to a website about the job. It explains the whole system and has monthly construction updates with pictures.

Ahh takes me back to my power station days.

Celtic you should try lining these motors up to the pumps using clock gauges and shimms. For some reason it was always the sparkies job.

What is that red cable strung between the motors? Looks like a temporary setup.

Nick,

I have done one of these GWR sites (Electrical System Design/Engineered, plus ran the job).

The Well Pump Motors were small - 5 and 7½ HP, 460V 3Ø - which were "scattered" all around the site.

There were 10 HP and 25 HP Transfer Pumps at the Equipment Compound, along with a tiny 2 HP Sump Pump.

Treatment of Water removed from the Aquifer was done on the Equipment Compound (H²O² "Hydrogen Peroxide" < 26% solution, being the only "near hazardous" chemical).

Ours was nothing compared to the site you are doing!!! [Linked Image]

Looks like the site is down in Fountain Valley at the I405 / Euclid-Ellis crush [Linked Image]

Scott, or anyone..what happens to the waste they remove from the water?

Does this go to the salt flats, or is this somehow reduced somewhere to it's orginal components?

The red cable is temporarily powering up the space heaters.
Scott, you are correct about the location. No problem for me since I moved down here. Don't even have to hit the freeway!
