Harmonic Study

Harmonic studies are performed to determine harmonic distortion levels and filtering requirements within a facility and to determine if harmonic voltages and currents are at acceptable levels.

Field measurements and computer simulations are used to characterize adjustable-speed drives (ASDs) and other nonlinear loads. Simulations are then performed to determine the filter specifications and effectiveness. The application of harmonic filters will significantly alter the frequency response of the power system. An evaluation of the harmonic voltage and current limits, (e.g., IEEE Std. 519) is completed to determine the effectiveness of the proposed filter installation.

Main Benefits of Conducting a Harmonic Study:

  • Avoids damage due to excessive harmonic currents in transformers and capacitor banks.

  • Ensures sensitive electronic equipment will not malfunction due to excessive harmonic voltage distortion.

  • Satisfies the utility’s voltage and current harmonic distortion requirements.
