A measurement technique for power system harmonics

摘要

A system that uses a hardware interface a PC, and advanced software to measure, analyze, and report the condition of the harmonics on the power system is described. It has the ability to measure the distortion on both the voltage and current of the power system. Following a review of harmonic characteristics, the measurement techniques, data acquisition, analyses and report generation, and use of the information are discussed. The system has greatly reduced the effort needed for a study.
