Hi all...
I'm working on a project that will involve to use an underground vault. I have never done this before so I'm looking for informations on how to size the vaults based on clearances. The design will involve 22.9KV (Pri) to 13.8KV (Sec) 7.5MVA transformer and one switchgear (one breaker) at the Primary side. Transformer Dimensions is 177"W x 125"D x 125"H, the 27KV switchgear is 36"W X 96"D x95"H. Any thoughts on how big the transformer needs to house these two equipments?Not sure what is the clearance around the transformer needed and not sure what is the recommended height of the vault. Your help really appreciated.
Thanks,
