Tab.18-6:
Harmonics HMV…E and HCS
Harmonics of Supply Units, Re‐
generative (HMV…R)
In the end application, the harmonics values are within the mini‐
mum and maximum values listed below. The harmonics values
depend on
●
Load distribution
●
Conditions in the mains
●
Mains pollution which other devices feed in the mains
If the degree of mains pollution generated by other devices is low,
the resulting values of the harmonics in the mains current of the
drive system are minimum values. If there is a high degree of
mains pollution generated by other devices, the maximum values
of the table can be reached in the worst case.
