Hi everyone,

a doubt about ETAP library for cables.

selecting a certain kind of cable from ETAP library, the impedance setting gives values for both Rl/R0 and Xl/X0. my question is: how does it calculate this value (i mean, the homopolar ones)?

I add a picture, taken from the Help instructions, where it can be written some references for the value, but i was not able to find those values consulting them!!

Can someone help me?
