A harmonic study is performed to determine if harmonic voltages and
currents are at acceptable levels. 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
studies should be considered whenever there are solid state drivers
or electric furnaces and capacitor banks in the power system.
