Describes a system involving a hardware interface, a PC, and advanced software to measure, analyze, and report the condition of harmonics on the power system. The results showed that the harmonic content of the load waveform affects power measurement significantly. It is possible with sample data techniques to determine true real power consumed by the power distribution system, or to resolve poor power factor questions. It is noted that the system developed for the measurement and analysis of harmonic effects on power metering has greatly reduced the effort needed to study and solve the problem of power measurement in the presence of harmonic distortion.
