Line Impedance Tables
This section has several tables of impedances for all-aluminum, ACSR, and copper constructions. All are based on the equations in the previous section and assume GMD = 4.8 ft, conductor temperature = 50°C, GMDfN = 6.3 ft, and earth resistivity = 100 W-m. All zero-sequence values are for a four-wire multigrounded neutral circuit.
