Harmonic and Flicker Testing
Harmonic and and Flicker Testing
Harmonic and flicker tests are performed to ensure that electrical and electronic equipment meet the emission and immunity requirements of international EMC and grid-compatibility standards. These evaluations verify that products neither introduce unacceptable harmonic distortion or voltage fluctuations into the power network, nor become susceptible to power-quality disturbances such as voltage variations, interharmonics, or frequency fluctuations.
Benefits of Harmonics and Flicker Testing
Prevent network distortion
Ensure that the equipment does not introduce excessive harmonic currents or voltage flicker that could destabilize power grids or affect other connected devices.
Improve system compatibility
Confirm that products operate correctly when exposed to distorted or unstable power conditions, ensuring immunity to real-world power quality disturbances.
Protect sensitive electronics
Reduce the risk of overheating, malfunction, or premature failure caused by voltage environments rich in harmonics or exhibiting flicker.
Increase field reliability and user experience
Minimize visible light flicker, unexpected resets, and functional anomalies in end applications.
Meet market access requirements
Provide accredited and traceable data required for CE marking and international EMC compliance for global product distribution.
Support robust product design
Early detection of emission and immunity issues helps engineers optimize power supplies, filters, and control algorithms before mass production.
