Abstract
LOS SISTEMAS DETECTORES DE FALTA DE NEUTRO SON LOS DENOMINADOS SDFN.1, SDFN, SDFN.N Y SDFN.111. CUANDO EL CONDUCTOR NEUTRO DE UN SISTEMA TRIFASICO DE DISTRIBUCION DE C.A., SE CORTA, EN LA MAYORIA DE LAS VECES, APARECEN SOBRETENSIONES EN LOS RECEPTORES MONOFASICOS A EL CONECTADOS, PRODUCIENDOLES AVERIAS, CONATOS DE INCENDIO, ETC., YA QUE LAS PROTECCIONES ELECTRICAS ACTUALMENTE EXISTENTES, NO REACCIONAN FRENTE A LOS INCREMENTOS DE TENSION CITADOS.COMPLEMENTANDO DICHAS PROTECCIONES CON SISTEMAS DETECTORES DE FALTA DE NEUTRO, ESTOS DETECTARAN LAS SOBRETENSIONES, ACTUANDO POSTERIORMENTE SOBRE ALGUNA PROTECCION YA EXISTENTE QUE DEJARA LOS RECEPTORES FUERA DE LOS EFECTOS DE LA SOBRETENSION.LA FIGURA 3 PUEDE SERVIR COMO REPRESENTACION DE DICHOS SISTEMAS, EN LA QUE EL MODULO 1 DETECTA LA SOBRETENSION, EL MODULO 2 ES INFORMADO DE DICHA SOBRETENSION TRANSMITIENDO LA EVENTUALIDAD AL MODULO 3, QUE ACTUARA SOBRE UNA PROTECCION EXISTENTE PARA QUE LIBERE LA SOBRETENSION QUE NOS OCUPA.
