Abstract
La presente solicitud se refiere a un procedimiento para la deteccion de magnitudes eléctricas de una red de tension alterna trifásica con una primera, segunda y tercera fase, que abarca los pasos de medir en cada caso un valor de la tension de las fases primera, segunda y tercera con respecto a un conductor neutro en un primer instante en el tiempo, transformar los tres valores de la tension del primer instante en el tiempo en coordenadas polares con una amplitud de la tension y un ángulo de fase, repetir la medicion y transformacion en al menos otro instante en el tiempo, y determinar la frecuencia, amplitud de la tension y/o el ángulo de fase, actuales, de al menos una de las fases a partir de los valores de la tension transformados en coordenadas polares.
