1.

What is Harmonics?

expand_more

Harmonics is a , integral multiples of the fundamental frequency, introduce distortion in non-sinusoidal voltage or current waves, quantified as Total Harmonic Distortion (THD) expressed as a percentage of the pure sine waveform.

2.

What is harmonic indices?

expand_more

In the power quality industry, specific index values, such as Total Demand Distortion and Total Harmonic Distortion, are instrumental in assessing service quality by gauging distortion caused by harmonics, serving as valuable metrics for evaluating system performance.

3.

What is voltage and current distortion?

expand_more

Voltage distortion refers to any deviation from the nominal sine waveform of AC line voltage, while current distortion is any deviation from the nominal sine waveform of AC line current.

4.
