Abstract

The results of a two-phase project regarding measurements of both voltage and current harmonics at numerous locations within a utility system are summarized. The voltage and current harmonics were measured, stored, and plotted at various substations during each phase of the project using a dynamic signal analyzer, a multipen plotter, and other data acquisition systems. This resulted in a total of 1120 measurements. Also, 24 h measurements were made at some locations to obtain time-of-day variations of the harmonic pattern. Various tables are presented to facilitate analysis of data and comparison of the voltage and current harmonics for multigrounded and unigrounded distribution systems and associated transmission lines
