Data collection and processing for digital AC power system monitor/analyzer

A digital monitor/analyzer (1) for an ac electrical power system (3) samples the current and voltage waveforms at a slow rate for performing metering functions, and at a high rate for analyzing harmonic content. Sampling is performed in sampling frames (35) comprising a plurality of repetitions (371...
