Abstract
DISPOSICION DE PROTECCION FRENTE A PERDIDAS DE FASES PARA UNA CARGA DE CORRIENTE ALTERNA POLIFASICA. A UN DETECTOR (14) DE INTENSIDAD DE CORRIENTE, CUYA SEÑAL DE SALIDA ESTA RELACIONADA CON LA INTENSIDAD EN EL CIRCUITO, VAN UNIDOS DOS CONDENSADORES QUE TIENEN CADA UNO SU PROPIO TRAYECTO DE SEÑAL, DE MODO QUE POSEEN DIFERENTES REGIMENES DE CARGA Y DESCARGA. DURANTE UNA CONDICION DE PERDIDA O FALTA DE FASE, UNO DE LOS CONDENSADORES SE DESCARGA MAS FACILMENTE QUE EL OTRO, Y SU TENSION EN BORNES SE HACE MAYOR QUE LA DEL OTRO. UN DETECTOR DE FALTA DE FASE ADVIERTE ESTA DIFERENCIA DE POTENCIAL, INICIANDOSE ASI UNA SEÑAL DE DESENGANCHE QUE PROVOCA LA APERTURA DEL CIRCUITO ELECTRICO.
