Elevator modernization - Utilizing higher voltage

Once in a while we see a building upgrade their power from 208/230 to 480 and they install a transformer in the elevator room to knock the power down.  During a modernization is the perfect time to order 480vac equipment and get rid of the transformer.

Benefits of higher voltage – The benefit is that is uses lower amperage, what you pay for on your power bill is the amperage usage.  You can use smaller more efficient motors and smaller motor starters.  See the table below

Voltage	HP	Amperage
230	30	76
480	30	38

In our case the building went to 480vac during a reconstruction project and left the elevator to be modernized at a later date.

We will be modernizing the elevator with 480VAC equipment and this will allow us to remove the transformer, put the hydraulic unit on the back wall and have lots of space for our elevator controller and power freight controller which currently are stacked on top of each other making it interesting to work on.  

[get your ladder or stool to work on the freight controller or perhaps it is that i'm short I cannot reach it]

The key here is communication and planning with the building owner.  We have a great building owner who is working with us through this project.
