Safety of the Personnel Working on Multicircuit Power Overhead Lines Implies the Precise Knowledge of the Magnetic Induced Voltages. Algorithm, Software and Comparison With Measurements At Real Scale

There is an increased need to perform some maintenance operations on a de-energized circuit of the multicircuit lines with other energized circuits. Applying the Std 524-2003 to calculate the magnetic induced voltages in the de-energized conductors does not solve the matter accurately. A precise algorithm and software were developed, modeling both the transversal and longitudinal geometric and electric parameters of the multi-conductor system, independent of the number of spans and conductors, comparisons with measurements being available, too
