Abstract :
Unsymmetrical spacing of conductors produces errors in the values of a-c resistance measured on the individual conductors, of a 3-conductor system, with 3-phase current. The average of two sets of 3-phase measurements, one with positive sequence current and the other with negative sequence current gives the true value of conductor resistance. An analysis given in the Appendix evaluates the effect of unbalanced inductive reactance upon the measured resistance. Experimental data are shown which support the analysis.
