Controlling harmonic issues in VSDs
When it comes to power quality in variable speed drives (VSDs), harmonic issues have no distinct benefit, and lead to lower operating efficiencies and higher energy costs. Steve Hughes, Managing Director of harmonic filter specialist REO UK, explores how engineers can control harmonic issues in VSDs, and how minimising harmonic interference leads to more efficient power consumption and a drop in energy used.
Contrary to what many think, not all harmonic interferences are bad. For example, the characteristic crunchy sound of the Marshall amplifiers that are seen at most rock and metal music shows is actually harmonic interference-laden noise.
