Supporting Upper and Lower Bus in Stations
Supporting Upper and Lower Bus in Stations
(OP)
I am reviewing a 138kV station design with a upper and lower 3" alum. bus. Normally to connect the two bus together we use 2 split angle 2" bus in a "v" form. This design however has a single 3" vertical connection. My question is will this weaken the overall bus and cause concern for vibration or is there no difference structurally.

The attached file which is taken from the ABB switchgear manual gives some insight on the calculations required.
