TSA is a third harmonic filter based on a insulation transformer with a star- triangle connection (D-Y), which eliminates third order harmonics and has a passive 5th order harmonic filter in the secondary panel. Therefore, this configuration eliminates third order harmonics from the neutral conductor and reduces 5th order harmonics.
Applications
Lines with the distribution of distorting singlephase loads, such as computers, discharge lamps, etc. Reduction of neutral overloads with the circulation of third order harmonics. Decrease in the installation's losses.
