Phoenix Sky Harbor International
Airport is the world's fifth busiest airport. The airport
serves more than 1,300 flights that take off and land daily with
approximately 108,200 passengers arrive and depart.
The
power system study was conducted in accordance with FAA
standard. The short circuit and protective device
coordination study were performed during the construction phase
of the project.
The new expansion will be served by
doubled ended 480V 3000A-bus switchgear. The double ended
sub will also be serve by a 900 KW generator in case of
emergency.
This project required selective coordination on critical circuits, with no overlap (including the instantaneous region). This degree of coordination was required through more than fifteen levels of indenture. Through careful product selection, Power Systems Engineering was able to provide this degree of coordination. |
