Total Harmonic Distortion Measurement

The total harmonic distortion (THD) is a measurement of the harmonic distortion and is defined as the ratio

between the power of the harmonic frequencies above the base frequency and the power of the base frequency.

The total harmonic distortions for current/voltage are calculated using the following formula.
