Page 3: Important Information
In order to commission the active harmonic filter, a good understanding of the working principle is mandatory. The following picture is showing the basic topology and the working principle of the RHF-Active. Active Harmonic Filters are parallel filter circuits injecting harmonics into the supply. These Harmonics have phase shift of 180°... - Page 4 RHF-Active injected harmonics. As a result, harmonics upstream of the RHF-Active will be low. The RHF-Active will inject a harmonic current of same amplitude and frequency, but reverse angle into the connection point. Therefore, the theoretical result of the THDi upstream of the RHF-Active is 0%, assuming that the filter is sized for the full THC (Total Harmonic Current).

- Page 7 2. Connection 2.4 Connection – Parallel setup RHF-Active filters rated >55A are constellation of parallel setups. When ordered this way the filters will be set for parallel operation by factory. Settings can be changed in system level. If the compilation of active filters are changed, it can be necessary to follow the parallel setups.
- Page 8 2. Connection Step two: Configure individual filters for parallel operation: In order to run RHF-Active in parallel, the individual filters must be set to the correct total compensation current connected (“Parallel total comp. Current [A]”). This setting can be done in system mode.

Page 13: Settings - Angle
4. Settings 4.2 Settings – Angle The RHF-Active is injecting harmonics of opposite angle, compared to the measured value. Deviation between measured value and injected value can be adjusted in the “Angle” settings. Values are referring to degree (2.20 correspond to an offset of 2.2° (injection angle 180°+2.2°)). Negative values are possible. -

“Harmonics (odd)”. Values are referring to a factor of the individual harmonic amplitude (1.05 correspond to compensation of 105%). This setting is used to fine-tune the performance of the RHF-Active. These settings can be changed during operation on the RHF-Active. -
