Explanation
• Selecting the Voltage/Current Grouping
The harmonics in IEC harmonic measurement are determined from the component of
each order and the interharmonics between the orders. You can select the computing
equation of the harmonic from the list below.
• OFF
Only the components of the integer multiples of the fundamental wave are
considered harmonic component of each order. Interharmonic components are not
included.
• Type1
The harmonic subgroup is considered a harmonic component of the corresponding
order.
• Type2
The harmonic group is considered a harmonic component of the corresponding
order.
