AixLib.Electrical.Transmission.Functions.R_AC_correction

# .AixLib.Electrical.Transmission.Functions.R_AC_correction

This function computes the correction factor of the DC resistance for AC systems at 60 Hz

## Information

This 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.
