Abstract
The computational resources of a digital power meter can be reduced by utilizing an interrupt requested in anticipation of interrupt latency to perform real-time tasks, an approximation of a root mean square load current at an earlier time to compensate for a phase shift between the load current and the current transducer output, and an amplitude that is neither zero nor maximum to distinguish the cycles of a harmonically distorted waveform.
