Substation Station bus Design
Substation Station bus Design
(OP)
Was wondering is anyone had any sources for determining the short cct capability of an existing substation bus design. It was originally designed through a consultant who went through another contractor and somehow any pertinent information on the bus design was never submitted (or was lost in the documentation process). In any case, I know what the sht cct levels will be on the busswork but I what I do not know is how to go about calculating the capability of the existing bus to withstand the forces generated during a short cct condition or what things in particular (like stn post insulators) limit that capability. The sht cct level will be going up in the next few years by about 30% of what once once assumed the ultimate so I want to ensure that the old desing will be adequate. Any hints, tips or references would be much appreciated.
