Harmonic Mitigating Transformers

PublishTime：2022-07-21

Harmonic Mitigating Transformers (HMT) accomplish harmonic mitigation (attenuation) (see “What are Harmonics?” on page 6) by providing good source impedance and through sine wave recombination. Sine wave recombination occurs within the transformer itself at the nodes, the connection points, of the windings. Sine wave recombination also occurs when the sine waves are phase shifted using multiple transformers. All of these methods may help reduce harmonics in electrical distribution systems.
While not intended as a complete technical analysis, this bulletin will highlight the appropriate application of HMTs. It is interesting to note that none of this is new technology. In variable frequency drive applications, harmonic mitigation has been accomplished with transformers for more than 50 years. Additional information regarding some of the theory of harmonic mitigation using transformers is included in the appendices.
