Title: Test methodology for mains interference frequency measurement
Keywords: Mains interference, Frequency measurement, Harmonic suppression.

Abstract: A test procedure for mains interference frequency measuring is represented in this work. The procedure is based on measurement of the transfer coefficient of an averaging digital filter applied to the interference signal. The procedure is implemented in MatLab environment. It includes filters for elimination of the DC offset, for suppression of the second and third harmonic and for measurement of the power-line interference frequency. Additionally, a procedure for measurement of the amplitude of the interference is developed.
