SELECTING RATINGS FOR CAPACITORS AND REACTORS IN APPLICATIONS INVOLVING MULTIPLE SINGLE-TUNED FILTERS

This paper focuses on the selection of ratings for capacitors and air- core reactors used in multiple single-tuned harmonic filter configurat ions. Digital transient simulations of an example power system demonst rate the exceptionally high voltage and current stresses placed upon f ilter components in these configurations. Design guidelines for increa sing the component ratings to account for the extra stresses are descr ibed. A comparison between traditional rating methods and the proposed methods are presented for the example system.
