Abstract

Método y sistema de discriminación de faltas a tierra en circuitos con transiciones línea aérea cable. La presente invención es un nuevo sistema de bloqueo de reenganche para faltas monofásicas a tierra en redes de energía eléctrica que cuentan con transiciones línea aérea - cable en las que dichos cables tienen las pantallas puestas a tierra en un solo punto. Este sistema discrimina si la falta monofásica a tierra se ha producido en la línea aérea o en el cable. En base a esta discriminación, el sistema permitirá el reenganche si la falta se ha producido en la línea aérea o bloqueará dicho reenganche si la falta se ha producido en el cable. Esta invención está orientada a redes de distribución de energía eléctrica con neutro puesto a tierra de forma rígida o a través de impedancia limitadora.
