Greeting
i have looked at several posts on this topic already, however none could give me the answer i am looking for.
I am interested in how to simply estimate the zero sequence impedanceof a cable.
I need the information for the option of fault location in the relays and the calculation of the short circuit currents.
Studying the literature so far in most cases, I found that a satisfactory estimate of the zero sequence is Z0 = 3 * Zd.
What were your experiences?
Thanks in advance
