ABSTRACT:
A device for an electrical power system having a nonlinear load. The circuit is connected in series with the nonlinear load and is tuned to the third harmonic of the power source frequency. The circuit substantially eliminates the harmonic currents and neutral currents located in the power system, and improves the power factor of the nonlinear load by optimizing the current drawn by the nonlinear load.
