Somebody mentioned that by changing the taps on a three phase transformer, it is possible to have a consumption saving.I do not agree cause, if the voltage goes up, the current will go down equally and supply the same amount of power.Is there an impedance savings or something I am missing?

Either way... you have posted in the wrong forum :)

I recommend Electric power engineering at http://www.eng-tips.com/threadminder.cfm?pid=238

This forum is for administrative/documentation configuration managment rather than a physical configuration change to your electrical box.
