Maximum bus fault
Maximum bus fault
(OP)
I know that the maximum fault current flows in a line can be during a contingency due to mutual inductance. That is for a line but can the maximum fault current seen at a bus ever be during a contingency or does it always decrease from the base case with any contingency?

"Never" and "Always" are terms best avoided when doing power system analysis.
RE: Maximum bus fault
You are talking about contingencies that can increase bus fault current. , but in your example the contingencies reduce bus fault current. I did not understand.

The cases may be very rare, but I'm pretty sure I'm remembering that it happened because it caused me so much consternation. A system configuration change since then (relocation of a bulk transformer) may have removed that possibility. Made coming up with relay settings a real bear when system normal isn't the worst case.
