Abstract :
The results are presented of a computer study of the impedance of direct buried cable with current flow in the earth taken into account. The cable considered is solid insulation, concentric neutral, primary cable used for rural underground distribution. The effects of earth resistivity, line length and neutral conductivity are examined. Impedance values for 15 kV and 25 kV cable are given for sizes # 2 through #4/0 AWG.
