What is a Harmonic and Flicker analyzer? 

Harmonic and Flicker Analyzer

Harmonic and Flicker analyzer is an electronic instrument used to detect and monitor the presence of harmonic and flicker transients. It is commonly used in EMC harmonic and flicker emission measurement testing on electrical and electronic equipment. This instrument tests electrical and electronic product compliance with standards such as IEC/EN 61000-3-2, IEC/EN 61000-3-3, JIS C61000-3-2, EN IEC 61000-3-11, and more. The design specification of the Harmonic and Flicker analyzer follows the IEC/EN 61000-4-7 and IEC/EN 61000-4-15.  

Harmonics are sinusoidal voltage or current waveforms with frequencies that are integer multiples of the fundamental frequency. Harmonics are generated by the operation of non-linear loads such as SMPS, discharge lighting, or saturated electric machines. When the harmonics are added to the utility power, produces a distortion on the normal voltage or current waveform. Flicker is the short-time voltage fluctuations in power supply typically caused by varying load currents. The flicker on the power supply may cause flickering issues (changes in brightness of light) in lighting systems. Both Harmonics and flickers affect the performance of sensitive electrical and electronic equipment.   

The Harmonic and Flicker analyzers are ideal for harmonic and flicker analysis for compliance testing of single-phase and three-phase equipment. These instruments are designed to comply with the standards of IEC/EN and JIS.
