Fault current through converter

[Kevin Mejia]

Hi everyone,
In a industrial voltage level, I want to know how the fault current magnitude changes when it passes through a 12-pulse converter.
Thanks!

Diodes cannot withstand high current passing through them. I am sure the converter is protected by Current Limiting, fast acting HRC fuses on AC side of the converter.
Thus, the fault current that can pass through the converter depends on the let-through current of the HRC fuses.
