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

www.arcadvisor.com and the site www.csemag.com. The cse
site has a series called "The Art of Protecting Electrical
Systems" it is a 31 issue? series. anyway they are on Part
#13 at their site which is downloadable.I hope I have helped.
