Abstract

La presente invención se refiere a un sistema que incluye un cable caliente y un cable neutro configurados para establecer un circuito cerrado entre una fuente de alimentación y una carga. El sistema incluye además primero y segundo transformadores, así como un sensor. El primer transformador de corriente está acoplado al cable caliente y está configurado para introducir una primera corriente de prueba, con una primera polaridad, en el cable caliente. El segundo transformador de corriente está acoplado al cable neutro y configurado para introducir de manera sustancialmente simultánea una segunda corriente de prueba en el cable neutro. La segunda corriente de prueba tiene la misma polaridad que la primera corriente de prueba. El sensor está configurado para detectar una asimetría entre las primera y segunda corrientes de prueba y está configurado además para causar la interrupción del circuito cerrado al detectar la asimetría.
