Functions:

• calc_l_int Calculates internal inductance of solid or tubular conductor
• calc_gmr Calculates geometric mean radius (GMR) of solid or tubular conductor
• carsons Calculates Carson's earth return correction factors Rp and Xp for self or mutual terms
• calc_self_z Calculates self impedance term (in Ohm/km)
• calc_mutual_z Calculates mutual impedance term (in Ohm/km)
• calc_dubanton_z Calculates Dubanton approximation for self or mutual impedance (in Ohm/km)
• calc_z_matrix Calculates primitive impedance matrix
• calc_y_matrix Calculates primitive admittance matrix
• calc_kron_z Calculates Kron reduced matrix

Features currently not supported:

• Skin effect calculation for internal self impedance
• Input data validation, e.g. check that all phase conductor vectors are the same size
