NOTE
The reduction of the low harmonic current
emission to the rated THiD implies that the
THvD of the non-influenced line voltage is
lower than 2% and the ratio of short circuit power
to installed load (R
SCE
) is at least 66. Under these
conditions, the THiD of the line current of the adjustable
frequency drive is reduced to 10% or 5% (typical
values at nominal load). If these conditions are not
or only partially fulfilled, a significant reduction of the
harmonic components can still be achieved, but the
rated THiD values may not be achieved.
