KAIC Calculation

[m sleem]

Hi everyone,
Which we considering for OCPD KAIC Calculation the asymmetric ka or symmetric ka , from my first calculation it seems the smaller i.e. symmetric. Am i right?

Any feedback

Symmetrical.

Thanks

But symmetric calculation takes into account asymmetric DC by a suitable factor. Isn't it?

I guess it depends on your application. For Medium Voltage (MV) and higher, I say you should consider subtransient (asymmetric).
