Circuit breaker short circuit calculation

Circuit breaker short circuit calculation

Circuit breaker short circuit calculation

(OP)
I am fairly new to this. I have to perform short circuit calculation for a MV-LV switchyard and help in circuit breaker and protection ratings. I understand that I need the following currents from my CS calculation:

- Initial Short-Circuit Current (I"k)
- Maximum Asymmetrical Fault or Peak Current (Ip).
- Breaking Fault Current (Ib)
- Steady State Fault Current (Ik)

I am looking for some online resources or short tutorials on the subject. Important things to notice and practical issues.

Thanks
R
