What is acceptable THD?

The limits on voltage harmonics are thus set at 5% for THD and 3% for any single harmonic. It is important to note that the suggestions and values given in this standard are purely voluntary. However, keeping low THD values on a system will further ensure proper operation of equipment and a longer equipment life span.

Is lower THD better?

The lower the THD percentage, the better.

In an ideal situation for use with headphones, speakers, and earphones, you would be looking for a total harmonic distortion level as close to zero as possible.

Can THD be greater than 100%?

The current THD can be higher than 100%. Use the total harmonic distortion THD(I) to assess the distortion of the current wave with a single number. The following table shows the THD limit values. Low harmonic currents: little risk of disturbance.

What is the THD of utility power?

At its most basic level, THD is a measure of how much your load is distorting the perfect waveform of the power provided by your utility.
