Harmonic emission in the power network - EN61000-3-2

This standard defines the limits of the distortion generated by the equipment on the sinewave of the power network. The objective of this test is to verify that the amplitude of the network harmonics within the range of 50 - 2000Hz (up to the 40th harmonic) is within the consented levels. This is done by inserting a current probe between the EUT and the DENEB Data Acquisition Board.

Harmonic Network Analyzer

The output signal of the DENEB current probe is connected directly to the DENEB Data Acquisition Board input. On activating the ¤Enab.FFT selector, the SPECTRUM programme carries out the real-time Fourier Analysis of the sampled signal, with video refresh of about once a second.
