Abstract

A matrix solution method is presented that enables the engineer to determine the phase current distribution among the individual conductors in parallel single-conductor power cables. Use of a commercial mathematics software package on a desktop MS-DOS personal computer to solve the resulting matrices is illustrated. Results of field measurements on a six-conductor-per-phase cable installation are compared with calculation results. Application of the results to cable assessment activities is discussed, including ampacity verification for increased loads, cable insulation life assessment studies, and cable impedance input into station service system analysis
