Meeting IEEE 5191992 Harmonic Limits
Using HarmonicGuard® Passive Filters
Written By: John F. Hibbard Michael Z. Lowenstein

loads, it became apparent that a rewrite of IEEE 519, treating the relationship of harmonic voltages to the harmonic currents flowing within industrialplants, was necessary to support control of harmonic voltages. The new IEEE 519, published in 1992, sets forth limits for both harmonic voltages on the utility transmission and distribution system and harmonic currents within the industrial distribution systems. Since harmonic voltages aregenerated by the passage of harmonic currents through distribution system impedances, by controlling the currents or system impedances within the industrial facility, one can control harmonic voltages on the utility distribution. Unfortunately, there is some user confusion regardingthe application and intent of the information included in IEEE 519, 1992. Section 10, “Recommended Practices for Individual Consumers” describes the current distortion limits that apply within the industrial plant. Consulting engineers and applications engineers may not be clear as tothe proper use of Table 10.3, which outlines the limits of harmonic distortion as a function of the nature of the electrical distribution system. This paper will explain, with examples, the proper use and interpretation of this table. Using a computer model, we have outlined the levelof distortion one might expect to encounter for various types of loads and distribution systems and the level of correction obtainable through the use of line reactors and passive harmonic trap filters has been detailed. It is hoped that the readers of this paper will come away with abetter understanding of the meaning and application of IEEE 519, 1992.

With the advent of IEEE 519-92, the increasing demand by utilities for power factor improvement, and the proliferation of non-linear loads in industrial power distribution systems, specification [continua]
