Each harmonic is calculated according to 1 1 100 and the total current harmonic distorsion for the harmonics measured is calculated according to 9 IY I I 10076 2 i where is the fundamental current and PA is the current for harmonic with number n At each measurement the harmonic is set to 0 if the rms value of the current is below a certain lower limit Note that as only the harmonics up to 500 Hz is measured and because the harmonics is measured one at a time is not a true total harmonic distorsion which would require that all harmonics up to infinite frequency would be measured and that all harmonics including the fundamental would be measured at the same time Note also that presence of harmonics over 500 Hz will result in folding distorsion as the sampling frequency is 1000 Hz The folding distorsion can affect the measurements below 500 Hz and give erroneous results Due to the possible presence of folding distorsion and the fact that the harmonics is measured sequentially one at a time it is recommended that the harmonic measurement results of the meter is used as a tool to detect presence of harmonics and not as an exact instrument to get very precise results In the event log function of the meter see section 2 12 5 it is possible to log presence of harmonics A percentage limit for the total harmonic distorsion of the harmonics measured is then set and the start time date and duration will be logged if this
