.AixLib.Electrical.Transmission.Functions.R_AC_correction .AixLib.Electrical.Transmission.Functions.R_AC_correctionThis function computes a correction factor for adapting the DC resistance when working with AC voltages. The correction factor assumes f = 60 Hz.
The correction is based on the type of cabel (AWG or kcmil) and the material.
