Abstract

Están descritos la metodología y el aparato de las materias específicas para proporcionar la funcionalidad mejorada de un medidor en un arreglo de comunicaciones de dos vías, tal como un sistema de medición avanzada (AMS) o una infraestructura (AMI). Más particularmente, la presente tecnología se refiere a metodologías y aparatos para proporcionar la percepción de carga para medidores de utilidad los cuales preferiblemente son operados con características de desconexión remota en un cuadro operacional abierto de infraestructura de medición avanzada (AMI). Los medidores para la presente materia específica utilizan un circuito de detección, y separadamente utilizan cierta funcionalidad de desconexión remota. En particular, la funcionalidad de desconexión está acoplada con consideración de la información de carga eléctrica, tal como la corriente de carga como se determinó por la funcionalidad de medición. Proporcionar tal funcionalidad permite lo siguiente todo de acuerdo con la presente materia específica: (a) ciclo de encendido/apagado frecuente del servicio eléctrico, (b) desconexión del servicio mientras que la corriente completamente calificada está siendo entregada a través de los contactos de interruptor, (c) la conservación de la integridad del contacto de interruptor por la operación de interruptor selectiva con base en la carga de corriente, y (d) proporcionar una funcionalidad de anulación inmediata y sí se necesita.
