Abstract

Un sistema y un método para detectar pérdida de fase de entrada en un regulador de velocidad ajustable (ASD) incluyen una unidad de entrada para detectar datos de operación del ASD. Los datos de operación incluyen una corriente de enlace DC del ASD. El sistema también incluye un observador de estado que está adaptado para recibir los datos de operación de la unidad de entrada y extraer una corriente de capacitor de enlace DC de ASD usando la corriente de enlace DC. El sistema también incluye un controlador programado para comparar la corriente de capacitor de enlace DC extraída con un rango de falla predeterminado y generar una indicación de falla de una pérdida de fase de entrada si la corriente de capacitor de enlace DC extraída está dentro del rango de falla predefinido. El controlador también está programado para calcular un lapso de vida estimado del capacitor de enlace DC con base en la corriente de capacitor de enlace DC extraída.
