The objective of this paper is to present performance peculiarities of industrial power systems using single-tuned filters for limiting harmonics and improving reactive compensation.

An industrial plant with existing harmonic problems was selected for investigation.

Measurements were performed to characterise the harmonic generation of the load. Computer software was used for an investigation of the filter harmonic problems.
