Abstract
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 of harmonic
mitigation has become common. Questions arise
regarding the performance of passive harmonic trap
filters in removing harmonic distortion.
Data from a number of TCI HarmonicGuard® trap filter
installations have been collected which illustrate how
closely IEEE 519-92 limits can be met.
HarmonicGuard® filters have been installed, both for
power factor improvement and to meet harmonic
distortion limits based on IEEE 519-92.
A computer model has been developed to help predict
the harmonic reduction that can be expected for
specific load-filter combinations and the model has
been verified with field data. This paper outlines and
explains the computer model and details the
application of harmonic trap filters. Computergenerated
design curves are provided which can be
used by a system designer to predict success in
meeting harmonic specifications using
HarmonicGuard® trap filters.
