本文提出一种能量测量前端，集成了原位背景全系统精度监测功能，能够在不中断测量的情况下持续监测电表的精度，解决了因元件老化和高压/电流事件导致的现场精度未知问题，避免了不必要的电表更换。
to determine billable energy consumption. These devices are factory calibrated, and then perform measurement without interruption over their lifetime. Once in the field their accuracy is unknown due to component aging and high voltage/current events[1]. Meters are periodically replaced as a preventive measure, leading to the unnecessary replacement of perfectly good meters while some inaccurate meters may remain in field. This paper presents an energy-measurement front-end that enables continuous background Condition Base Monitoring (CbM) over the lifetime of a meter. Crucially it monitors the performance of its voltage and current sensors, which are typically the largest sources of inaccuracy and drift. During normal operation, small test signals (“stimuli”), with adaptable but well-defined
