A more accurate algorithm and software to calculate the magnetic induced voltages in multiconductor systems

Because of the necessity to perform maintenance on one of the circuits of the high and very high tension double circuit lines that have one of the circuits operational, a case that lately becomes more frequent, the calculation of the currents and induced tensions in the circuit´s conductors that is under induction is required to establish safety working conditions. This paper does not intend to modify the standardized established limits for touching tensions in normal conditions or short circuit of the inductor conductor, but proposes a mathematical model and the associated software that will give more precise results than those resulting from applying the methodology and software from IEEE Std. 524-2003 annexes.
