Power derating - altitude above sea level 1000 m (3280 ft) without derating. 1000–4000 m (3280–13123 ft) with derating 5% per 1000 m
(3280 ft).
Table 7.1 General Technical Data
1) THDi level is system level performance from the filter combined with the actual frequency converter.
NOTICE
The reduction of the low harmonic current emission to the rated THDi implies that the THDv of the non-influenced
mains voltage is lower than 2%, and the ratio of short circuit power to installed load (R
SCE
) is above 66. Under these
conditions, the THDi of the mains current of the frequency converter 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 THDi values may not be observed.
