Abstract

Seven day-measurements of harmonic current and voltage made at the main buses of industrial, commercial, and residential customers are reported. The results are for a large residential load, an accounting operations building, a welded pipes plant, a passing and machining plant, a large supermarket, and a retail store. The results are representative of low-voltage buses in the northeast US. At all the locations it was found that 99% of the time the voltage total harmonic distortion was much smaller than 5% limit recommended by IEEE Std 519. The data provide the initial core of documentation for future reference and follow-up of the trends in harmonic levels at end users
