Dear All seniors，
I try to calculate the phase series impedance from the tline configuration. I check the formula in the EMTDC handbook and I can not understand the formula:
Zii=jw.u0/2pi*(ln(Dij/dij)+0.3565*ec/(pi*r^2)+ec*M*coth-1(0.777*r*M)/(2*pi*r).........
Please help me to find the reference "The Theory of Natural Modes in Multi-Conductor Transmission Systems" or other papers to understand the formula.
Thanks for your help
