Explanation
When determining the measurement functions Uhdf, Ihdf, Phdf, Uthd, Ithd, and Pthd
of the harmonic measurement mode, select the denominator of the equation from the
choices below. For the equations, see section 7.11.
• 1/Total
The denominator is the measured data of all orders from the minimum measured order
(0
th
or 1
st
) to the maximum measured order (within the upper limit of the measured
order).
• 1/Fundamental
The data of the fundamental signal component (1
st
order) become the denominator.
Note
The minimum and maximum harmonic orders to be measured are the values selected in
section 7.6.
