This factor value does respect, besides respecting each harmonic component’s voltage value,
distribution of harmonic components of different orders across their spectrum and it addresses the
effect of voltage values. It is thus a more convenient value to determine total load of a capacitor by
current. If the nominal value voltage is undistorted, this factor is at value of 100%. The following table
shows CHL factor values for a few selected scenarios of harmonic distribution at fundamental
harmonic component nominal value.
