how to size DC circuit breaker

how to size DC circuit breaker

how to size DC circuit breaker

(OP)
hydrogenerator 83MVA-13.8kV use static excitation system with DC circuit breaker.
Power converter unit will comprise  3-phase bridges of six-pulses silica thyritors.
Excitation system report figure out:
1-short circuit at the converter output: 23.7kA (peak current)
2- maximum breaking current capacity: 10kA for DC circuit breaker.
My question: what is the correlation between these values?



 

RE: how to size DC circuit breaker

I would suggest moving this question to the Electric Power forum.  The guys and gals that lurk there are more apt to deal with this type of question.
