Para entender este fenómeno y analizar posibles soluciones, se modela el mismo en DIGsilent Power y se muestra el efecto negativo del fenómeno en el correcto funcionamiento de estas protecciones. Las posibles soluciones a los problemas que introduce la inducción mutua de secuencia cero en el trabajo de las protecciones (67N y 21N) son analizadas; notando en la mayoría de los casos, que las soluciones no resultan efectivas del todo, ya que estas no eliminan completamente todas las dificultades que el fenómeno de inducción mutua de secuencia cero introduce al trabajo de las protecciones de líneas paralelas y su costo es por lo general elevado.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In this article, a study of the main errors that introduces mutual zero sequence induction in the work of directional overcurrent and ground distance protections (67N and 21N), when they are protecting parallel transmission lines, is carried out. To understand this phenomenon and analyze possible solutions, it is modeled in DIGsilent Power and the negative effect of the phenomenon on the proper functioning of these protections is shown. The possible solutions to the problems introduced by the zero sequence mutual induction in the work of the protections (67N and 21N) are analyzed; noticing in most cases, that the solutions are not effective at all, since these do not completely eliminate all the difficulties that the phenomenon of mutual induction of zero sequence introduces to the work of parallel line protections and its cost is therefore high overall.]]></p></abstract>
