| Popis: | SUMMARY In this article, the formulas derived using the symmetrical components for calculating magnetic flux density near a three-phase twisted cable carrying a three-phase unbalanced load were proposed. To effectively mitigate the magnetic flux density from power lines, we used the three-phase four-wire twisted cables. These cables use the location exchange of conductors by twisting the phase cables with each other to mitigate the positive-sequence and negative-sequence magnetic fields as well as to neutralize the zero-sequence magnetic fields through the current in the neutral wire, thereby achieving the goal of reducing magnetic fields. This study shows that using three-phase four-wire twisted cables can effectively reduce the power frequency magnetic fields, especially in multiple-circuit feeder systems.
