Network Bank
This photo is a 7 ton crane being put together on the roof of a 37 story building. It is all lattice and with a 90 degree boom. It was brought up to the roof by Iron Workers in pieces through the freight elevator. It will be powered by a 480 three phase motor and will be reeved three parted. The purpose of this crane is to bring an unassembled 30 ton crane to the roof and be assembled. The purpose of all this is to change out a transformer bank that is on the 37th floor.
Here are two of the transformers and the third of the bank is behind me, they are 1500KVA.

It kinda makes sence. devide the load evenly and limit line loss. try and push secondary voltage too far and it makes problems for everyone. We have to maintain secondary voltage between 114 -125v and 228- 250... its a very narrow window in the summer when demand is at its peak.

Re: Network Bank
Hey if its 100 volts be happy you got something because it's a 100 better then zero!
I'm showing 128/128/126 when it's 91 degrees--whats likely my problem?

Kooman, I have been there too, but with today’s tools I bet you have a Polaris Ranger to get to places you can not get a truck. This project has been worked on for over a year now.

Correct, by having the transformer vault at the top of the building helps with line loss, but remember on a network System if any bank goes out no one will ever loose power. The Lights stay on 24-7!
