Fault Level comparison
Fault Level comparison
(OP)
In a Short Circuit Study, the fault level in the different busbars and his contributions are known.
If we think in the contribution of any circuit, only one part of the short circuit current, will flow through the switchgear in this busbar.
It is correct to take the fault level from the busbar to verify the capacity of the switchgaer?, Or only the contribution from these circuit?, Or it is necessary to calculate the fault level “after” the switchgear?
Any help and references are appreciated!

IEC 60909 is a common standard, there are others with which I am not sufficiently familiar to comment.
