Abstract

Un relé protector se red digital muestra la corriente polifásilica, la tension de red y la tension de fase. y preferiblemente 32 veces por ciclo, de modo que se eliminan hasta que el séptimo armonico y el decimoquinto armonico, respectivamente del cálculo de secuencia usado para efectuar decisiones de disparo y cierre. El relé también provee medicion, proteccion de sobrecorriente directa y una característica anti-bombeo, la ultima trabando el disyuntor si se excede un numero seleccionado de operaciones del disyuntor durante un intervalo de tiempo dado. El muestreo secuencial de la corriente y tensiones polifásicas por medio de un solo convertidor análogo digital (25) reduce el costo de relé, para acomodar la medicion y la extraccion de los componentes fundamentales de la corriente y tensiones para los cálculos de secuencia, la corriente polifásica y la tension de red son muestras esencialmente en un primer orden por polifásica y la tension de red son muestreadas secuencialmente en un primer orden por un numero dado de ciclos y luego en un segundo orden inverso por el mismo numero dado de ciclos.
