Shunt filters are effective in minimizing voltage distortion caused by nonlinear loads in industrial power systems. Different alternatives of filter design should be considered before making the final decision on filter configuration. Among the criteria used for performance evaluation are losses, current, and voltage ratings of each of the filter components, and the effect of filter and system contingency conditions. The design and performance of single-tuned and high-pass filters and the methodology used for the analysis will be discussed.
